ping_after_nyet
Host Generation Only.
If TRUE, the Exerciser automatically generates
PINGs (and retries) after receiving a NYET instead of
the expected_pid. This feature is only used if the
expected_pid is an ACK. PINGs are retried until an
ACK is received. When the PING is ACKed, the
Exerciser generates a new frame before continuing
with the Gen File.
If FALSE, the Exerciser continues as if an ACK
occurred.
This statement can also be used in conjunction with
any pid=xxx statement in the .utg file. This can be
done to override the configured or default retry
behavior.
Syntax example: ping_after_nyet=TRUE
