Correct sk_forward_alloc handling for error_queue would need to use a
backlog of frames that softirq handler could not deliver because socket
is owned by user thread. Or extend backlog processing to be able to

Add a mutex_unlock missing on the error path.  In each case, whenever the
label out is reached from elsewhere in the function, mutex is not locked.

14 years agofs_enet: Adjust BDs after tx error

fs_enet: Adjust BDs after tx error

This patch fixes an occasional transmit lockup in the mac-fcc which
occurs after a tx error.  The test scenario had the local port set
to autoneg and the other end fixed at 100FD, resulting in a large
number of late collisions.

According to the MPC8280RM 30.10.1.3 (also 8272RM 29.10.1.3), after
a tx error occurs, TBPTR may sometimes point beyond BDs still marked
as ready.  This patch walks back through the BDs and points TBPTR to
the earliest one marked as ready.

Tested on a custom board with a MPC8280.

IPv6: fix Mobile IPv6 regression

Commit f4f914b5 (net: ipv6 bind to device issue) caused
a regression with Mobile IPv6 when it changed the meaning
of fl->oif to become a strict requirement of the route
lookup.  Instead, only force strict mode when
sk->sk_bound_dev_if is set on the calling socket, getting
the intended behavior and fixing the regression.
