From: Maya Erez Date: Fri, 22 Feb 2019 14:20:59 +0000 (+0200) Subject: wil6210: remove rtap_include_phy_info module param X-Git-Tag: v5.1-rc1~178^2~33^2^2~6 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=387f3794b8cfbdfe6e627978ae4aec92b91b5fb8;p=linux.git wil6210: remove rtap_include_phy_info module param Due to a HW issue in PHY info collection rtap_include_phy_info is not in use, hence can be removed.
