[PATCH net-next v2 3/8] net: qlogic: qede: Use linkmode helpers for EEE

From: Andrew Lunn
Date: Wed Feb 14 2024 - 18:15:22 EST


Make use of the existing linkmode helpers for bit manipulation of EEE
advertise, support and link partner support. The aim is to drop the
restricted _u32 variants in the near future.
