[dpdk-dev] [PATCH 09/11] net/atlantic: use capability bits to detect eeprom access

[Igor Russkikh]

From: Pavel Belous <pavel.belous at aquantia.com>

Its better to use capability bits FW provides to detect whether
firmware has APIs for EEPROM access.

Before that explicit FW version comparison was used and that may
cause conflicts.
