Hi, thank you for reporting this.
Please use [email protected]. Added it to CC:
ipv6 value is supported.
> match.set_ipv6_src(ipsrc)
This line caught my eyes.
What type is ipsrc? The serializer expects the value to be '!8H'.
Not bytearray/str of 16byte length. Nor single integer.
I guess that ipsrc is different from what the serializer expects.
So conversion is needed before passing set_ipv6_src().
(Clean up is going on right now.)
from ofproto_v1_3_parser.py,

thanks,
