[dpdk-stable] [PATCH v5 07/17] net/i40e/base: fix update link data for X722

[Robin Zhang]

The X722 card has 'Link Type' information elsewhere than the X710.
Previously, for all cards, the 'Link Type' information was retrieved by
opcode 0x0607 and this value was wrong for all X722 cards.
Now this information for X722 only is taken by opcode 0x0600
(function: i40e_aq_get_phy_capabilities) instead of an opcode
0x0607 (function: i40e_aq_get_link_info).
All other parameters read by opcode 0x0607 unchanged.

Fixes: e6691b428eb1 ("i40e/base: fix PHY NVM interaction")
Fixes: 75c3de654ead ("net/i40e/base: fix long link down notification time")
