Hi Dave,
   This patch (1/2) seems to have fallen through the cracks. The other
one (2/2), you already picked.
Thanks

Just to make sure, let me please mention that c009f413b79de52 and
9a00b697ce31e are very much needed in stable kernel. Without these we
couldn't install any OS over network.

Thanks.

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

[jassisinghbrar]

From: Jassi Brar 

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.
