configured. This patch disables MSI-X until the issue is root caused.

The tx timeout routine was waking the tx queue conditionally. However,
it must call it unconditionally since the dev_watchdog has halted the tx
queue before calling the timeout function.

From 4305b541357ddbd205aa145dc378926b7cb12283 Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo <acme@redhat.com>

Subject: [SK_BUFF]: Convert skb->end to sk_buff_data_t

Now to convert the last one, skb->data, that will allow many simplifications
and removal of some of the offset helpers.
