net: lantiq: Wake TX queue again
[ Upstream commit dea36631e6f186d4b853af67a4aef2e35cfa8bb7 ]
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.
