[PATCH v6 0/5] wifi: brcmfmac: add FT/OKC fast roaming offload support

[Jason Huang <Jason.Huang2@infineon.com>]

From: Jason Huang <jason.huang2@infineon.com>

Hi,

This series adds nl80211 and brcmfmac support for firmware fast roaming
offload covering FT and OKC.

Some Broadcom/Infineon firmware can offload FT or OKC roaming without
advertising full 802.1X 4-way handshake offload. The series adds a new
nl80211 extended feature bit for this capability, lets userspace install
and delete PMK material when the driver advertises it, and wires the
capability through brcmfmac based on firmware FBT/OKC support.

For brcmfmac, the series tracks FBT and OKC firmware capabilities, keeps
the firmware supplicant profile state distinct for roaming offload, passes
PMK material to firmware for FT/OKC, and reports port authorization after
successful offloaded roaming.

Changes in v6:
- Rename the nl80211 extended feature to
  NL80211_EXT_FEATURE_FAST_ROAM_OFFLOAD to better describe that userspace
  offloads fast-roaming handling to the driver/firmware. The feature covers
  both FT and OKC.
- Reorder the nl80211 PMK capability checks to avoid the line-length
  warning.
- Allow nl80211_del_pmk() for FAST_ROAM_OFFLOAD-only drivers, matching
  nl80211_set_pmk(), so userspace can delete PMK material it was allowed to
  install.
