[dpdk-dev] [PATCH] ixgbe: fix reta query and update on x550

[Wang Xiao W]

For x550 device, the reta table has 512 entries, but in function
ixgbe_dev_rss_reta_query and ixgbe_dev_rss_reta_update we use an
"uint8_t i" to traverse the entries, this will lead the function
to an endless loop.

This patch changes the data type from uint8_t to uint16_t to fix
the issue.

Fixes: 4bee94a6c22f ("ixgbe: support 512 RSS entries on x550")
