[PATCH v2 3/3] net/e1000: fix Rx and Tx queue status

[Qiming Yang]

Igb driver don't enable queue start/stop functions, queue status is not
updated when the HW queue enabled or disabled. It caused application can't
get correct queue status.
This patch fixes the issue by updating the queue states when the queue is
disabled or enabled.
