Subject: net/ixgbe/base: use 8 bits for PCI functions
X-Git-Tag: spdx-start~6360
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=3c5c9e096b83d53b050bc3ecf98673d00435b039;p=dpdk.git

net/ixgbe/base: use 8 bits for PCI functions

Since PCIe standard defines maximum of 8 functions per device lan_id
is a value 0..7. Because of that, lan_id don't need to be u16.
