Re: [PATCH 1/5] ucc_geth: Reduce IRQ off in xmit path

Joakim Tjernlund [off-list ref] :

Currently ucc_geth_start_xmit wraps IRQ off for the
whole body just to be safe.
Reduce the IRQ off period to a minimum.

It opens a window in ucc_geth_start_xmit where the skb slot in
ugeth->tx_skbuff[txQ] is set and T_RA has not been written into
the descriptor status. Consider a racing poll : the !skb test in
ucc_geth_tx may not work as expected.
