Subject: [PATCH net-next 1/6] qlge: Fixed packet transmit errors due to potential driver errors.

From: Jitendra Kalsaria <jitendra.kalsaria@...gic.com>

qlge driver was acting wrongly when considering TX ring full
as a TX error. TX ring full is expected behavior when NIC is
overwhelmed and is expected to happen, as far as packets are
not lost.
