From: Hauke Mehrtens Date: Sat, 12 Sep 2020 19:36:26 +0000 (+0200) Subject: net: lantiq: Wake TX queue again X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dea36631e6f186d4b853af67a4aef2e35cfa8bb7;p=linux.git net: lantiq: Wake TX queue again The call to netif_wake_queue() when the TX descriptors were freed was missing. When there are no TX buffers available the TX queue will be stopped, but it was not started again when they are available again, this is fixed in this patch.
