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)
