[dpdk-dev] [PATCH] enic: fixed possible data loss in vnic_dev.h

[Maciej Gajdzica]

In function writeq is written in two 32-bit long registers with writel
function. When trying to write val >> 32, static code analysis tool
reports that 64-bit value is passed to function expecting 32-bit value.
Added cast to clear this warning.
