Hey Guys,
Is the rev_chap_name_len field in the ibft_tgt structure set to zero? if so
we should not be scanning for the reverse CHAP name in fwparam_ibft as a
zero in rev_chap_name_len effectively indicates that there is no reverse
CHAP username. If the field is a non zero value then this is likely a
firmware bug. Could you please post an entire iBFT dump from the failure
case?
Thanks,
Supreeth
