net: davinci_emac: Fix interrupt pacing disable
[ Upstream commit d52bcb47bdf971a59a2467975d2405fcfcb2fa19 ]
This patch allows to use 0 for `coal->rx_coalesce_usecs` param to
disable rx irq coalescing.
Previously we could enable rx irq coalescing via ethtool
(For ex: `ethtool -C eth0 rx-usecs 2000`) but we couldn't disable
it because this part rejects 0 value:
if (!coal->rx_coalesce_usecs)
return -EINVAL;
Fixes: 84da2658a619 ("TI DaVinci EMAC : Implement interrupt pacing functionality.")
