Replaces snapshot-of-tx_tail comparison in the watchdog with a
tx_stall_tail_moved flag set/cleared under tx_ptr_lock. Avoids
the index-aliasing false-positive Phil Elwell flagged on the
raspberrypi/linux PR review.
Anchored against the rpi-6.18.y vendor fork so it applies cleanly
on top of patches 0001..0003. See talos-kernel-patches/0004-*.patch
for the mainline-anchored variant intended for netdev v2.
For readers landing on the public repo, document:
* what the three patches do and what bug they target
* link to the upstream netdev submission (lore archive)
* link to the Cilium / Ubuntu launchpad issue trackers
* how the rpi-fork-targeted version here differs from the
mainline-targeted version on netdev (5-line macb.h hunk variation
for the vendor fork's extra bool tx_pending field)
* license: GPL-2.0-only (kernel-derived) overriding the harness's MIT
* how to add additional patches (drop a *.patch file; sorted apply
order)
No code changes.
Three-patch series targeting the BCM2712/RP1 (Raspberry Pi 5)
silent TX hang documented at:
* https://github.com/cilium/cilium/issues/43198
* https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2133877
0001: flush PCIe posted write after TSTART doorbell
0002: re-check ISR after IER re-enable in macb_tx_poll
0003: add TX stall watchdog fallback for lost TCOMP
New patches live in patches/linux/ and are copied into
checkouts/pkgs/kernel/build/patches/ via a new 'patches-linux'
Makefile target, wired into the existing 'patches' aggregate.
Verified to apply cleanly against raspberrypi/linux @ f2f68e79f16f
(the ref pinned by the preceding commit).
