|

+ MyLoader is a bootloader which allows the user to define partitions
|

+ in flash devices, by putting a table in the second erase block
|
||||
+ on the device, similar to a partition table. This table gives the
|
||||
+ offsets and lengths of the user defined partitions.
|
||||
+
|
||||
+ If you need code which can detect and parse these tables, and
|
||||
+ register MTD 'partitions' corresponding to each image detected,
|
||||
+ enable this option.
|
||||
+
|
||||
+ You will still need the parsing functions to be called by the driver
|
||||
+ for your particular device. It won't happen automatically.

The mask indicates the bits one wants to zero out, so it needs to be
|

inverted before applying to the original TOS field.

sch_sfq: fix sfq_enqueue()
|
||||
|
||||
commit 8efa88540635 (sch_sfq: avoid giving spurious NET_XMIT_CN signals)
|
||||
forgot to call qdisc_tree_decrease_qlen() to signal upper levels that a
|
||||
packet (from another flow) was dropped, leading to various problems.
|
||||
|
||||
With help from Michal Soltys and Michal Pokrywka, who did a bisection.

This patch allows the user to specify desired packet types (outgoing,
|
||||
broadcast, unicast, etc.) on packet sockets via setsockopt.
|
||||
This can reduce the load in situations where only a limited number
|
||||
of packet types are necessary
