The test include:
- configuration on vrouter side with mrgbuf off and GSO/GRO on
409f19a7 ==> 0100 0000 1001 1111 0001 1001 1010 0111 -- > connectivite OK
- configuration on vrouter side with mrgbuf on and GSO/GRO off
409f8027 ==> 0100 0000 1001 1111 1000 0000 0010 0111 -- > connectivite NOK
In all the cases, the VNF send the following bits :
430020 => 0000 0000 0100 0011 0000 0000 0010 0000 (mrgbuff, TSO)
and in all cases, the negotiated feature bit is :
30020 => 0000 0000 0000 0011 0000 0000 0010 0000
The question is why if the result is the same, in one side when the mrgbuf off and GSO/GRO on the connectivity is Ok and when mrgbuf on and GSO/GRO off the connectivity is NOK ?
