f1b9d77912 ramips: Minor ramips_esw.c cleanup
Stop handling VLAN setup in the kernel.
Removes the obsolete RT305X_ESW_VLAN_CONFIG_BYPASS option I added for
WL-351 and add some extra comments.
Also removes the en_vlan per-port flag that isn't very useful really, it now
is only controlled by the global enable_vlan flag.

3b17f1deb8 ramips: Add swconfig support to ramips_esw.c
Add swconfig support to ramips_esw.c

This patch adds swconfig support for ramips_esw:

Tested on both D-LINK DIR-300 B1 and Sitecom WL-351 (external
rtl8366rb on internal port 5).
I've made sure that in the enable_vlan=0 case it behaves like a dumb
switch, so external switches should work fine with vlans and
verified this on the WL-351.

The current state shown by swconfig is always read directly from HW
registers, new settings only show after 'swconfig dev rt305x set apply'.

e4720dfa95 ramips: Add byte queue limits support to net/ethernet/ramips_main.c
Add byte queue limits support to net/ethernet/ramips_main.c

"Byte queue limits are a mechanism to limit the size of the transmit
hardware queue on a NIC by number of bytes. The goal of these byte
limits is too reduce latency (HOL blocking) caused by excessive
queuing in hardware (aka buffer bloat) without sacrificing
throughput."

a2708d11e8 ramips: Rework ramips_eth to not require irqsave locking anymore
Previously the tx housekeeping was done in a spin_lock_irqsave critical
section which causes irqs to be disabled during that time. Since the
housekeeping is already prepared to be scheduled as a tasklet process
the housekeeping only in softirq context and revise the locking between
the tx path and the housekeeping tasklet by using a normal spin_lock
which in most situations will be a NOP anyway.

This makes sure that interrupts are only disabled for a short time
since in the worst case the housekeeping might have to free up to 256
skbs.

7b1e525b56 ramips: initial support for Sitecom WL-351 v1 002
This add support for the Sitecom WL-351 v1 002.
In principle the Engenius ESR9850 should also work with this, but I
don't have the hardware to test it.

Since an external gigabit switch (RTL8366RB) is used,
I had to modify the ramips_esw driver to add a 'bypass' mode, which
just configures it to not filter the vlan tags.
Also two initialization words (FCT2 and FPA2) are set to different
values by u-boot than what the driver is using and it only seems to
work correctly when they not overridden by the driver, so I
added them to the platform specific data as reg_initval_fct2 and
reg_initval_fpa2.

With this wired lan works as expected, however I'm still having some
trouble with the wireless lan:
It only works after I rmmod & re-insmod rt2800pci and then
reconfigure it in the webinterface, but not directly after
rebooting.

The symptom of this is wpad saying:
Dec 20 15:45:09 OpenWrt daemon.info hostapd: wlan1: STA <notebookmac> IEEE 802.11: associated (aid 1)
Dec 20 15:45:09 OpenWrt daemon.info hostapd: wlan1: STA <notebookmac> WPA: pairwise key handshake completed (RSN)
Dec 20 15:45:22 OpenWrt daemon.info hostapd: wlan1: STA <notebookmac> IEEE 802.11: authenticated

But wpa_supplicant on the client saying:
Authentication with <wl351mac> timed out.

d14e9e706e ramips: Fix bridging in ramips ethernet driver
Bridging between the ramips ethernet driver and rt2800pci was somewhat
broken. Frames received by the ethernet driver which were passed to the
wifi driver for transmission were sometimes corrupted or sent out with
huge delays.

The reason for this is the missing assignment of skb->tail in the ramips
ethernet driver's rx path resulting in skb->tail pointing to skb->data.
Since skb->tail is used by mac80211 it writes into skb->data which messes
up the frames content.

Fix this by using skb_put to correctly set skb->len and skb->tail.
