Description

irx_err Output 1

Indicates an errored packet. This signal is valid only when both

irx_num_valid[7:4] and irx_eopbits[3:0] are non-zero. When a

CRC24 or other error occurs, the 100G Interlaken IP core asserts this

signal for all open channel packets to label them all as errored packets,

because the IP core cannot assign the error to a specific channel.
