4-13
Error insertion using an error code is done at the end of a packet. The
worst test case for the receiving decoder occurs when any of the symbols
listed in the following table are received, with the exception of EGP (end
of good packet).
Sending four running disparity errors within 16 symbol clocks amounts
to a check whether the InfiniBand link automatically reinitializes (see
the table below).
