Hello:

This series was applied to netdev/net.git (main)
by Jakub Kicinski [off-list ref]:

Now the traffic is handled in threaded IRQ, and the
disable_traffic flag is checked before handling the

buffer may leak, if threaded IRQ interrupts the
trasmit path midway.

With this change, disable_traffic and waiting_tx_skb
pointer are protected by spin lock/unlock pair.
