Excuse the newbie question...
What is the relationship between OFED and in-kernel infiniband drivers?
Is ofed the source of merges? If yes, why is there need for an external
development this time, why are drivers not developed within the kernel
like it is for all other drivers?
Is there more

communicate with which do not have direct InfiniBand connectivity.
IPoIB is still heavily used in

Newer Mellanox cards have most of the offloads you see for ethernet so
they get better performance
The router is fitted with one ConnectX2 QDR HCA and one dual port Myricom 10G
Ethernet adapter.

Here are some numbers:
- 1 IPoIB stream between client and router: 20 Gbits/sec
Looks OK.
- 2 Ethernet streams between router and server: 19.5 Gbits/sec
Looks OK.
