From e1fd9070729765910b144ffcf74ca199c766509b Mon Sep 17 00:00:00 2001 From: Linas Vepstas Date: Mon, 11 Jun 2007 13:59:21 -0500 Subject: 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.
