[PATCH v2 13/20] net/txgbe: fix link stability for 40G NIC
Zaiyu Wang
zaiyuwang at trustnetic.com
Wed Apr 29 12:25:07 CEST 2026
The link was previously configured via firmware, but this approach
resulted in unstable link behavior. To resolve the issue, re-add the
PHY configuration flow directly into the driver.
Fixes: ead3616f630d ("net/txgbe: support PHY configuration via SW-FW mailbox")
