- Add the BCM4322X D11 core revision and missing BCM43224 PCI device ID to our device tables. - Disable the DMA engine parity check (rather than adding parity support to the to-be-replaced bwn(4) DMA implementation). Currently, N-PHY support in bwn(4) is GPL licensed, and is not included by default. Until this is replaced with Broadcom's ISC-licensed N-PHY implementation, bwn(4) must be rebuilt to enable N-PHY support. To build bwn(4) with N-PHY support, add the following lines to your kernel configuration file and rebuild the kernel (and modules): options BWN_GPL_PHY To test bwn(4) with a BCM43224/BCM43225 device, install the firmware from the net/bwn-firmware-kmod port, and place the following lines in loader.conf(5): hw.bwn_pci.preferred="1" if_bwn_pci_load="YES bwn_v4_ucode_load="YES" bwn_v4_n_ucode_load="YES" bwn_v4_lp_ucode_load="YES" Approved by: adrian (mentor, implicit) Sponsored by: The FreeBSD Foundation
