[ovs-dev] [PATCH] dpif-netdev: Rename "size" variable to "cnt".

[Cian Ferriter]

Commit 72c84bc (dp-packet: Enhance packet batch APIs.) changed how the amount
of packets to be processed is retrieved. In the process, the patch used "size"
as the variable holding the amount of packets rather than "cnt". Change this
back to match with the "emc_processing()" comment.

Alternatively the comment above "emc_processing()" could be changed:
-/* Try to process all ('cnt') the 'packets' using only the exact match cache
+/* Try to process all ('size') the 'packets' using only the exact match cache
