Subject: wl12xx: move last_tx_hlid into wlvif
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4438aca9e16901d8d32a025ca27ad8284a117e09;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

wl12xx: move last_tx_hlid into wlvif

move last_tx_hlid into the per-interface data, rather than
being global.
