ixgbe: Fix RSC completion delay causing Rx interrupts to stop
When a user disables interrupt throttling with ethtool on 82599 devices,
the interrupt timer may not be re-enabled if hardware RSC is running. The
RSC completions in hardware don't complete before the next ITR event tries
to fire, so the ITR timer never gets re-armed. This patch increases the
amount of time between interrupts when throttling is disabled (rx-usecs =
0) when the hardware RSC deature is enabled.
