10-Gigabit Ethernet PCS/PMA (10GBASE-R/10GBASE-KR) v4.1 - PMA or PCS Reset during MDIO transaction could result in missed operation

Description

When using the 10-Gigabit Ethernet PCS/PMA (10GBASE-R/10GBASE-KR) v4.1 or earlier, a 'soft' PMA or PCS reset causes the MDIO interface logic to be reset. 

If this happens during an MDIO access, this might result in the MDIO operation being missed.

Solution

This has been resolved in v4.1 (Rev. 1) of the 10-Gigabit Ethernet PCS/PMA (10GBASE-R/10GBASE-KR) core.
