07e1d88d7b kernel: avoid underscore in *6lowpan package names
Packages kmod-bluetooth_6lowpan and kmod-ieee802154_6lowpan contain an
underscore in the package name.  This causes problems in package/install
because when building a list of package files to install offline using
opkg, it uses a wildcard of the form $(dir)/$(pkg)_*.ipk.

If you were to select kmod-bluetooth=y, but kmod-bluetooth_6lowpan=m,
the latter would be picked up by that wildcard, and make package/install
would fail:

Collected errors:
 * satisfy_dependencies_for: Cannot satisfy the following dependencies
 * for kmod-bluetooth_6lowpan:
 *      kmod-6lowpan
 * opkg_install_cmd: Cannot install package kmod-bluetooth_6lowpan.

Changing the wildcard pattern is not trivial, and there may be other
places in the build system making this assumption about the package name
format.

Using a dash in place of the underscore avoids the issue.

7d7aa2fd92 brcm2708: rename target to bcm27xx
This change makes the names of Broadcom targets consistent by using
the common notation based on SoC/CPU ID (which is used internally
anyway), bcmXXXX instead of brcmXXXX.
This is even used for target TITLE in make menuconfig already,
only the short target name used brcm so far.

Despite, since subtargets range from bcm2708 to bcm2711, it seems
appropriate to use bcm27xx instead of bcm2708 (again, as already done
for BOARDNAME).

This also renames the packages brcm2708-userland and brcm2708-gpu-fw.

9e0aab44b6 kernel: use older kernel for explicitly setting dependencies
It is generally more desirable to use older kernel versions for
dependencies, as this will require less changes when newer kernels
are added (they will by default select the newer packages).

Since we currently only have two kernels (4.14 and 4.19) in master,
this patch applies this logic by converting all LINUX_4_19 symbols
to their inverted LINUX_4_14 equivalents.

82a741c774 mac80211: switch to upstream owl-loader driver
The Owl Loader (named after the codename that Atheros gave
these devices back in the day) has been accepted upstream.

This patch removes the "misc" driver OpenWrt had and adds
the remaining differences against the version that ships
with 5.4-rc1 into a separate "120-owl-loader-compat.patch"
file that can be cut down once AR71XX is being dealt with.

Note: I decided to keep the existing (kmod-)owl-loader
package name around for now. The kernel module file in
the kmod package will be called ath9k_pci_owl_loader.ko
though.

b8a72dfd28 kernel: backport act_ctinfo
ctinfo is a new tc filter action module.  It is designed to restore
information contained in firewall conntrack marks to other packet fields
and is typically used on packet ingress paths.  At present it has two
independent sub-functions or operating modes, DSCP restoration mode &
skb mark restoration mode.

The DSCP restore mode:

This mode copies DSCP values that have been placed in the firewall
conntrack mark back into the IPv4/v6 diffserv fields of relevant
packets.

The DSCP restoration is intended for use and has been found useful for
restoring ingress classifications based on egress classifications across
links that bleach or otherwise change DSCP, typically home ISP Internet
links.  Restoring DSCP on ingress on the WAN link allows qdiscs such as
but by no means limited to CAKE to shape inbound packets according to
policies that are easier to set & mark on egress.

Ingress classification is traditionally a challenging task since
iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
lookups, hence are unable to see internal IPv4 addresses as used on the
typical home masquerading gateway.  Thus marking the connection in some
manner on egress for later restoration of classification on ingress is
easier to implement.

Parameters related to DSCP restore mode:

dscpmask - a 32 bit mask of 6 contiguous bits and indicate bits of the
conntrack mark field contain the DSCP value to be restored.

statemask - a 32 bit mask of (usually) 1 bit length, outside the area
specified by dscpmask.  This represents a conditional operation flag
whereby the DSCP is only restored if the flag is set.  This is useful to
implement a 'one shot' iptables based classification where the
'complicated' iptables rules are only run once to classify the
connection on initial (egress) packet and subsequent packets are all
marked/restored with the same DSCP.  A mask of zero disables the
conditional behaviour ie. the conntrack mark DSCP bits are always
restored to the ip diffserv field (assuming the conntrack entry is found
& the skb is an ipv4/ipv6 type)

e.g. dscpmask 0xfc000000 statemask 0x01000000

|----0xFC----conntrack mark----000000---|
| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
| DSCP       | unused | flag  |unused   |
|-----------------------0x01---000000---|
      |                   |
      |                   |
      ---|             Conditional flag
         v             only restore if set
|-ip diffserv-|
| 6 bits      |
|-------------|

The skb mark restore mode (cpmark):

This mode copies the firewall conntrack mark to the skb's mark field.
It is completely the functional equivalent of the existing act_connmark
action with the additional feature of being able to apply a mask to the
restored value.

Parameters related to skb mark restore mode:

mask - a 32 bit mask applied to the firewall conntrack mark to mask out
bits unwanted for restoration.  This can be useful where the conntrack
mark is being used for different purposes by different applications.  If
not specified and by default the whole mark field is copied (i.e.
default mask of 0xffffffff)

e.g. mask 0x00ffffff to mask out the top 8 bits being used by the
aforementioned DSCP restore mode.

|----0x00----conntrack mark----ffffff---|
| Bits 31-24 |                          |
| DSCP & flag|      some value here     |
|---------------------------------------|
			|
			|
			v
|------------skb mark-------------------|
|            |                          |
|  zeroed    |                          |
|---------------------------------------|

zone - conntrack zone

control - action related control (reclassify | pipe | drop | continue |
ok | goto chain <CHAIN_INDEX>)

7c50182e0c kernel: backport act_ctinfo
ctinfo is a new tc filter action module.  It is designed to restore
information contained in firewall conntrack marks to other packet fields
and is typically used on packet ingress paths.  At present it has two
independent sub-functions or operating modes, DSCP restoration mode &
skb mark restoration mode.

The DSCP restore mode:

This mode copies DSCP values that have been placed in the firewall
conntrack mark back into the IPv4/v6 diffserv fields of relevant
packets.

The DSCP restoration is intended for use and has been found useful for
restoring ingress classifications based on egress classifications across
links that bleach or otherwise change DSCP, typically home ISP Internet
links.  Restoring DSCP on ingress on the WAN link allows qdiscs such as
but by no means limited to CAKE to shape inbound packets according to
policies that are easier to set & mark on egress.

Ingress classification is traditionally a challenging task since
iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
lookups, hence are unable to see internal IPv4 addresses as used on the
typical home masquerading gateway.  Thus marking the connection in some
manner on egress for later restoration of classification on ingress is
easier to implement.

Parameters related to DSCP restore mode:

dscpmask - a 32 bit mask of 6 contiguous bits and indicate bits of the
conntrack mark field contain the DSCP value to be restored.

statemask - a 32 bit mask of (usually) 1 bit length, outside the area
specified by dscpmask.  This represents a conditional operation flag
whereby the DSCP is only restored if the flag is set.  This is useful to
implement a 'one shot' iptables based classification where the
'complicated' iptables rules are only run once to classify the
connection on initial (egress) packet and subsequent packets are all
marked/restored with the same DSCP.  A mask of zero disables the
conditional behaviour ie. the conntrack mark DSCP bits are always
restored to the ip diffserv field (assuming the conntrack entry is found
& the skb is an ipv4/ipv6 type)

e.g. dscpmask 0xfc000000 statemask 0x01000000

|----0xFC----conntrack mark----000000---|
| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0|
| DSCP       | unused | flag  |unused   |
|-----------------------0x01---000000---|
      |                   |
      |                   |
      ---|             Conditional flag
         v             only restore if set
|-ip diffserv-|
| 6 bits      |
|-------------|

The skb mark restore mode (cpmark):

This mode copies the firewall conntrack mark to the skb's mark field.
It is completely the functional equivalent of the existing act_connmark
action with the additional feature of being able to apply a mask to the
restored value.

Parameters related to skb mark restore mode:

mask - a 32 bit mask applied to the firewall conntrack mark to mask out
bits unwanted for restoration.  This can be useful where the conntrack
mark is being used for different purposes by different applications.  If
not specified and by default the whole mark field is copied (i.e.
default mask of 0xffffffff)

e.g. mask 0x00ffffff to mask out the top 8 bits being used by the
aforementioned DSCP restore mode.

|----0x00----conntrack mark----ffffff---|
| Bits 31-24 |                          |
| DSCP & flag|      some value here     |
|---------------------------------------|
			|
			|
			v
|------------skb mark-------------------|
|            |                          |
|  zeroed    |                          |
|---------------------------------------|

Overall parameters:

zone - conntrack zone

control - action related control (reclassify | pipe | drop | continue |
ok | goto chain <CHAIN_INDEX>)

cd3b298533 omap24xx: Remove unmaintained target
This target only supports kernel 4.1, which is not supported in OpenWrt
any more for multiple releases. It also looks like there is no active
maintainer for this target.
Remove the code and all the packages which are only used by this target.

To add this target to OpenWrt again port it to a recent and supported
kernel version.
