I'm bisecting to find the cause of the receive issue, but it's going to
take a long time (in the mean time, I can't do any mainline work.)

So far, the range of good/bad has been narrowed down to 6.14 is good,
1b98f357dadd ("Merge tag 'net-next-6.16' of
git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next") is bad.

14 more iterations to go. Might be complete by Sunday. (Slowness in
building the more fully featured net-next I use primarily for build
testing, the slowness of the platform to reboot, and the need to
manually test each build.)
