Subject: spidernet: service TX later.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e1fd9070729765910b144ffcf74ca199c766509b;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

spidernet: service TX later.

When entering the netdev poll routine, empty out the RX
chain first, before cleaning up the TX chain. This should
help avoid RX buffer overflows.
