Subject: [PATCH] net/ixgbe: fix too many interrupts
[ upstream commit 874f79102d2a15dd50293082842006fbc06572c7 ]
To support kernel VF, PBA bit is always set. But it may
cause the too many interrupts issue on specific Linux
kernel versions, e.g. 4.4.0-116.
PF host should set the auto clean, mask and throttling
as we always set the register for kernel VF.
Fixes: 6b75183ac4d0 ("net/ixgbe: fix wrong PBA setting")
