Details:

In Aurora 64b66b mode ([TOP_AURORA_TX|AURORA_TX_CONFIG:AURORA_TX_CONFIG_PROTOCOL_SEL = 1), TOP_AURORA_TX:AURORA_TX_UDP_SIZE=4 and AURORA_TX_UDP_CONFIG_PACK_MODE_SEL = 1 (TWP) is not supported.

For Aurora64b66b and TWP pack mode, other udp sizes (eg 1,2,3,5,6,7,8……so on) are supported, only udp size=4 isn’t supported.

Workaround(s):

None. For Aurora64b66b and TWP pack mode, other udp sizes (eg 1,2,3,5,6,7,8……so on) are supported, only udp size=4 isn’t supported.

Therefore we need to ask users/customers to not use udp_size=4 with this combination. *Therefore valid udp sizes are -*

*Aurora 8b10b and Aurora 64b66b-*

* AURORA_TX_UDP_CONFIG_PACK_MODE_SEL = 0 (Bytes) : Valid Udp sizes - AURORA_TX_UDP_SIZE = 8, 12, 16, 20.....so on

* AURORA_TX_UDP_CONFIG_PACK_MODE_SEL = 1 (TWP) : Valid Udp sizes - AURORA_TX_UDP_SIZE = 5, 6, 7, 8.....so on
