X-Git-Tag: hostap_2_11~2251
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1646883f43d160a62a06205df6cfa7e208751308;p=thirdparty%2Fhostap.git

Introduce a new vendor command
QCA_NL80211_VENDOR_SUBCMD_RATEMASK_CONFIG. This is used to set the rate
mask config to be used in MCS rate selection per PHY type.
