JabberErrors
Frames bigger than the maximum allowed, with
either a bad CRC or a non-integral number of
octets. The default maximum allowed is 1518
bytes untagged and 1522 bytes tagged, but the
value can be changed by a register.
Frames bigger than the larger of
2*maxframesize and 50000 bits are not counted
here, but counted in the VeryLongError counter.

RuntErrors
The total number of packets received that are
less than 64 octets in length, but longer than or
equal to 96 bit times.
Note: The “ShortRuntsThreshold” Register
controls the byte count used to determine the
difference between Runts and Shorts, and
therefore controls which counter is incremented
for a given frame size. This counter is only
updated after receipt of two good frames.
Port_Index

RR
0x00000000
Short Errors
The total number of packets received that are
less than 96 bit times, which corresponds to a 4-
byte frame with a well formed preamble and
SFD. This counter indicates fragment sizes
illegal in all modes, and is only fully updated after
reception of a good frame following a fragment.

2. When sending in large frames, the counters can only deal with certain limits. The behavior of the
LongErrors and VeryLongErrors counters is as follows: VeryLongErrors counts frames that are
2*maxframesize, dependent on where the maxframesize variable is set. If maxframesize sets greater than
half of the available count in RxOctetsBad (2^14-1), VeryLongErrors is never incremented, but LongErrors
is incremented. This is due to a limitation in the counter size, which means that an accurate count will not
occur in the RxOctetsBAD counter if the frame is larger than 2^14-1.
