Subject: ixgbe: Default to 1 pool always being allocated
Patch-mainline: v4.16-rc1
Git-commit: a8e87d9f7371e3ce026f1d0c01ebccb782b1285f
References: bsc#1101674 FATE#325150 FATE#325151
We might as well configure the limit to default to 1 pool always for the
interface. This accounts for the fact that the PF counts as 1 pool if
SR-IOV is enabled, and in general we are always running in 1 pool mode when
RSS or DCB is enabled as well, though we don't need to actually evaluate
any of the VMDq features in those cases.
