However, while this may explain the transmit slowdown because it's
on the transmit side, it doesn't explain the receive problem.

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.)
