Subject: carl9170: claim to support IBSS RSN.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e2d75c136f8df4a4e28ece75c475a65b9292729a;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

carl9170: claim to support IBSS RSN.

On carl9170, HW encryption is disabled on IBSS; the mac80211
software-based encryption is used instead. As mac80211 supports IBSS
RSN (per-STA GTK), claim its support in the carl9170 PHY.
