Aksh Garg says:

====================
Fix IET verification implementation for CPSW driver

The CPSW module supports Intersperse Express Traffic (IET) and allows
the MAC layer to verify whether the peer supports IET through its MAC
merge sublayer, by sending a verification packet and waiting for its
response until the timeout. As defined in IEEE 802.3 Clause 99, the
verification process involves up to 3 verification attempts to
establish support.

This patch series fixes issues in the implementation of this IET
verification process.
