[dpdk-dev] [PATCH v2 26/33] i40e/base: Reassign incorrect PHY type as a workaround for a FW issue

[Helin Zhang <helin.zhang@intel.com>]

The FW for SW3E is incorrectly reporting a breakout cable as PHY
type 0x3 when it should be 0x16 (I40E_PHY_TYPE_10GBASE_SFPP_CU).
As this is supposed to be fixed in the next FW version
(FW versions >= 4.4), if we get this value back from FW and the
version is < 4.4, reassign it to I40E_PHY_TYPE_10GBASE_SFPP_CU.
