poll the register for Tx/Rx interrupt

Hi!

     My servers use  82599ES 10-Gigabit adaptor.

I want to poll the register for the Tx/Rx interrupt events (MSI-x mode). From the 82599 datasheet, i know the registers are  EICR(1) and EICR(2) . But i can not get the addresses of EICR(1) and EICR(2).

Can everybody give the the addresses of EICR(1) and EICR(2) to me? Thanks.
