# 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)
