Subject: iwlwifi: add new TLV capability flag for BT PLCR
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0522588d2fdc7813338d2f02aec6e46dbc20431f;p=linux-beck.git

iwlwifi: add new TLV capability flag for BT PLCR

Packet Level Co-Running is a BT Coex feature which is
supported on certain devices only, hence the need for
a TLV flag for it.
