[dpdk-dev] [PATCH v3 1/2] net/ixgbe: fix x550 code to handle unidentified PHY

[Luca Boccassi <bluca@debian.org>]

ixgbe_identify_sfp_module_X550em() was missing the code to handle
unidentified PHY that has been there in 82599 so it was not able to
complete initialization of ixgbe sequence if no sfp plugged in.
Port it over to return an appropriate type and complete init sequence
properly.

Fixes: d2e72774e58c ("ixgbe/base: support X550")
Cc: stable@dpdk.org

v2: refresh to remove merge conflict with master
v3: coalesce fix into ixgbe_identify_sfp_module_X550em to avoid
    code duplication, improve comment
