<font size=2 face="sans-serif">Hi Mohan,</font><br><br><font size=2 face="sans-serif">Thanks your information. I see there
is restriction check in OVS flow classifier driver, but you can see that
in the flow classifier table, the column logical_source_port nullable is
false, this affects every driver.</font><br><br><font size=2 face="sans-serif"><br><br><br>Regards,<br>Juno Zhu<br>IBM China Development Labs (CDL) Cloud IaaS Lab<br>Email: nazhu@cn.ibm.com<br>5F, Building 10, 399 Keyuan Road, Zhangjiang Hi-Tech Park, Pudong New District,
