+Cc Maxime Chevallier, who now maintains stmmac; the MAINTAINERS
handover postdates the CC list of the original posting, sorry for the
omission.

Maxime: this is a repost of a fix originally sent on 2026-07-06,
reposted at Jakub's request after the netdev patch queue overflowed.
The previous posting, including the review discussion with Maciej
Fijalkowski on whether frame-based coalescing could be dropped
entirely, is here:
