Change Details

Initial work tested against a PCI BCM4312 (SSB) device. Once committed to HEAD, request that existing bwn(4) users tracking HEAD switch to if_bwn_pci, enable `hw.bwn_pci.preferred="1"`, and report any regressions they hit.

Tested against the following devices currently supported by bwn(4)/siba_bwn(4): BCM4312 BCM4318 BCM4321 With minimal changes to the DMA code, was able to bring up working Wi-Fi on following BCMA-based devices: BCM43224 BCM43225 Once committed to HEAD, request that existing bwn(4) users tracking HEAD switch to if_bwn_pci, enable `hw.bwn_pci.preferred="1"`, and report any regressions they hit.
