[dpdk-dev] [PATCH] doc: include ixgbe rx error changes

[Harry van Haaren]

This patch updates the release notes to include the changes
made (by me), which were not appropriatly documented at the time.
Hence, this patch fixes a number of missing docs,

Fixes: e81a315e5dc5 ("ixgbe: add MAC short packet discard count to Rx errors")
Fixes: 48dd1a82a615 ("ixgbe: remove mac fault counts from Rx errors")
Fixes: 256ff05a9cae ("ixgbe: fix Rx errors statistics for UDP checksum")

Also, the CRC byte removal was not added to release notes, so
Fixes: 156c5a8cf913 ("e1000: remove CRC size from byte counters")
Fixes: c03fcee9abbd ("ixgbe: remove CRC size from byte counters")
Fixes: 0834d1524dee ("i40e: remove CRC size from byte counters")

Apologies for the oversight - I have a cheat-sheet now :)
