Subject: e1000/base: fix EEPROM access for i210
X-Git-Tag: spdx-start~8336
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b4e5e60cbe64415d1aae9fb0194df7fa34223a7f;p=dpdk.git

e1000/base: fix EEPROM access for i210

The i210 has two EEPROM access registers that are located in
non-standard offsets: EEARBC and EEMNGCTL. EEARBC was fixed previously
and EEMNGCTL should also be corrected.
