New Revision: 312854
URL: https://svnweb.freebsd.org/changeset/base/312854
Log:
[net80211] prepare configuration checks for VHT, fragment-offload and
seqno-offload.
* allocate an ext bit for fragment offload. Some NICs (like the ath10k
hardware in native wifi or 802.3 mode) support doing packet fragmentation
in firmware/hardware, so we don't have to do it here.
* allocate an ext bit for VHT and start using it.
