Fix a race when multiple sockets are simultaneously calling sendto()
when the completion ring is shared in the SKB case. This is the case
when you share the same netdev and queue id through the

Following on from my previous RFC[1], this series adds two ioctl calls
to the ppp code to implement "channel bridging".
When two ppp channels are bridged, frames presented to ppp_input() on
one channel are passed to the other channel's ->start_xmit function for
transmission.
The primary use-case
Add documentation of the newly-added PPPIOCBRIDGECHAN and
PPPIOCUNBRIDGECHAN ioctls.

This new ioctl pair allows two ppp channels to be bridged together:
frames arriving in one channel are transmitted in the other channel
and vice versa.
The practical use for this is primarily to support the L2TP Access
Concentrator use-case. The end-user session is presented as a ppp
channel (typ

Hm, Jesper was suggesting two helpers, one that you implemented for things

To rectify above, it wasn't for each packet but per ICE_RX_BUF_WRITE
cleaned frames (16).

MRU.
Enable MTU normalization for this reason.
