commit a32802d07dc0ef95854abd892ccba7b016a7490f Author: Bjoern A. Zeeb <[email protected]> AuthorDate: 2026-02-10 21:22:03 +0000 Commit: Bjoern A. Zeeb <[email protected]> CommitDate: 2026-02-26 23:07:02 +0000 brcm80211: import Broadcom wireless brcmsmac and brcmfmac drivers This version is based on git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git e5f0a698b34ed76002dc5cff3804a61c80233a7a ( tag: v6.17 ). We are likely only going to use the brcmfmac driver but given they come nicely packaged in a directory structure and bwn(9) still uses GPL-only phy files we could use some of the information from brcmsmac and fix that (should it ever still be relevant).
