[os] fix failing ethernet link on micro

Silicon Errata Issues
Module 1:
Device fails to link after Asymmetric Pause capability is set
DESCRIPTION
Whenever the device's Asymmetric Pause capability (Register 4h, Bit [11]) is set to 1, link-up may fail after a link-up to
link-down transition (e.g., a cable disconnect).
END USER IMPLICATIONS
The device may fail to establish link when the Asymmetric Pause capability bit is set to 1.
Work around
Do not enable (set to 1) the Asymmetric Pause capability bit. If enabling this bit is required, a second link-up
attempt (e.g., disconnect and reconnect cable) is required to establish link.
PLAN
This erratum will not be corrected in a future revision.
