errors on traffic received to E810 port

[PCohen]

Hi

I have a program listening for traffic on a one of the ports on the E810(quad-port).

There are occasionally errors when reading from the file descriptor bound to this interface. (POLLERR)

When traffic is slightly higher, the errors occur very often - resulting in very high CPU usage.

I do not have this issue with other controllers such as X710-DA2 and 82599ES.
