Patches + build scripts + firmware sources to make the Broadcom BCM43224
(PCI 0x14e4:0x4353, subvendor 0x106b:0x00d1) work on FreeBSD 15.1.
Fixes:
- Fix 1: compile GPL N-PHY code (BWN_GPL_PHY build wiring)
- Fix 2: NULL-guard bwn_dma_ringfree on partial attach
- Fix 3: wire bwn_update_mcast to ic->ic_update_mcast
- Fix 5: load bwn_v4_n firmware at loader stage (loader.conf)
- Fix 6: reclaim pending TX frames at bwn_dma_stop (detach double-free)
- Fix 7: driver-owned node ref + remove dr_usedslot early-return +
bhndb_pci BHNDB_PCI_QUIRK_NO_MSI for BCM43224 (legacy INTx)
- Fix 8: restrict reclaim to TX rings only (RX reclaim caused heap
corruption / TCP panic)
README.md = rebuild guide (apply.sh + build.sh, manual steps)
RESEARCH.md = root-cause investigation log (Fixes 5-8)

# Apply the bwn BCM43224 (Apple MacBook Air A1370) patches to a clean
|
|
# FreeBSD 15.1 source tree. Idempotent: it skips any patch that is already
|
|
# applied.
|
|
#
|
|
# Usage: sudo ./apply.sh [SRC_ROOT]
|
|
# Default SRC_ROOT=/usr/src
|
|
#
|
|
# The patches:
|
|
# patches/patch-if_bwn.c - driver fixes (Fixes 1-4, 6-8)
|
|
# patches/patch-Makefile - GPL PHY build wiring (Fix 1)
|
|
# patches/patch-bhndb_pci.c - NO_MSI quirk for BCM43224 (Fix 7)
|
|
# patches/patch-bhndb_pcivar.h - NO_MSI quirk definition (Fix 7)
