* Refactoring to prepare multi-queues support, no intended behavior change:mpi2020-02-041-13/+22
| | | | | | | | | | | | | | | | | | - Abstract the allocation/freeing of TX/RX ring into em_dma_malloc(). This will ease the introduction of multiple rings. - Split the 82576 variant out of 82575. The distinction is necessary when it comes to setting multiple queues. - Change multiple TX/RX related macro to take an index argument corresponding to a ring. Currently only the index 0 and 1 are used. - Gather and print more stats counters - Switch to using a function, like FreeBSD, to translate 82542 registers and get rid of a set of defines. Tested by many, thanks! ok mlarkin@, jmatthew@
