- 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"

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
* always allocate maximum size txhdr entries
* set the right rx header offset/framesize based on firmware
This still isn't what's completely required for fw 598 support; there's
more to come.
Tested:
* Apple BCM94321MC 11abgn NIC, 11a STA mode, firmware version 4xx.
Obtained from: DragonflyBSD (txhdr entry sizing), fw 598 RX header size (linux b43)
* Add the siba bus phy/mac/bandwidth clock definitions (TGSLOW*)
* Add the PHY-N register gateway (BWN_PHY_N())
* Add the PHY-N TX phystat1 register - we need to actually fill out
more of the PHY encoding information when we assemble a frame.
* Various ancillary stuff
Nothing uses this yet, but I do have CCK/OFDM somewhat working
in 2GHz mode on a PHY-N device.
Obtained from: b43 (definitions)
o uses v4 firmware instead of v3. A port will be committed to create
the bwn firmware module.
o supports B/G and LP(low power) PHYs.
o supports 32 / 64 bits DMA operations.
o tested on big / little endian machines so should work on all
architectures.
It'd not connected to the build until the firmware port is committed.
