[dpdk-dev] [PATCH v2 04/30] net/ixgbe/base: fix PHY identification for x550a

Wed Dec 21 10:47:48 CET 2016
Method to identify the CS4223/CS4227 is incorrect and unreliable.
Provide a new register to differentiate between these PHY SKUs.
Fixes: fc0559bdb5e3 ("net/ixgbe/base: add link MAC setup for X550a SFP+")
