ixgbe: fix RSS limit for X550
[ Upstream commit e9ee3238f8a480bbca58e51d02a93628d7c1f265 ]
X550 allows for up to 64 RSS queues, but the driver can have max
of 63 (-1 MSIX vector for link).
On systems with >= 64 CPUs the driver will set the redirection table
for all 64 queues which will result in packets being dropped.
