> 
> Ixgbe based 82598 and 82599 have different priority recieve link-on register
> addresses. This is solved in base/ by providing in the PXONRXC and
> PXONXCNT as seperate macros. This patch ensures the correct address is
> read, avoiding reading garbage values.
> 
> Also PXON2OFFCNT doesn't exist in 82598, so it is not read for that MAC.
> 
> This issue has existed since the drivers were imported into DPDK, but was
> not easily discoverable as xstats were not available.
> Tested using testpmd> show port xstats all
> 
> Fixes: af75078fece3 ("first public release")
