Subject: [PATCH 1/2] net: netsec: enable tx-irq during open callback

From: Jassi Brar <jaswinder.singh@...aro.org>

Enable TX-irq as well during ndo_open() as we can not count upon
RX to arrive early enough to trigger the napi. This patch is critical
for installation over network.

Fixes: 533dd11a12f6 ("net: socionext: Add Synquacer NetSec driver")
