Phil Sutter says:

====================
net: Convert drivers to IFF_NO_QUEUE and cleanup afterwards

This series converts in-tree users away from the old and deprecated
'tx_queue_len = 0' idiom, adds a warning to notify out-of-tree driver
maintainers that there is need for action on their behalf and finally drops any
workarounds in scheduling algorithm implementations.
====================
