Subject: [net-next 10/10] ixgbe: refactor initialization of feature flags

From: Emil Tantilov <emil.s.tantilov@...el.com>

This patch reshuffles the switch/case structure of the flag assignment to
allow for the flags to be set for each MAC type separately. This is needed
for new HW that does not have feature parity with older HW.
