TX packets are now sent when we have a full packet of when the FIFO is full.
Last can always be asserted from user-side when packet needs to be immediately
transmitted, the behavior will then be similar to previous implementation.
Errors are now also reported on RX.
Without setting the ref clock domain to None, generation failed:

* in some cases, the delayed sink data was updated even though
sink was not valid, leading to corrupted source data
* this broke etherbone reads with DW=64
Pass through last_be or create a new one based on the length if needed
Initialize count at dw//8 and don't subtract source_length since it
could lead to underflow for very short packets. In case source.length is
not dw aligned, count will not be equal, so adjust comparison for that.
Crib last_be Case lookup from mac/sram.py
* only send a ping reply to type 8 (ping request) packets
* otherwise liteeth would send a ping reply to
`destination unreachable` packets too, which is not wanted
Removes a slightly inappropriately named VCD dump created by the XGMII
tests which may or may not have been a result of some frustration
during the test implementation. :)
