Subject: sfc: populate the timer reload field
Patch-mainline: v4.16-rc1
Git-commit: 0bc959a95e8c1ee0295d2b85538a2a32b7b87880
References: bsc#1105555 FATE#326117
The timer mode register now has a separate field for the reload value.
Since we always use this timer with the reload (for interrupt moderation)
we set this to the same as the initial value.
Previous hardware ignores this field, so we can safely set these bits
on all hardware that uses this register.
