Hi, have 2 mellanox adapters with direct connection CX4 cable.

After a few trials got the inifiniband working with SRP/RDMA from windows linux (opensm).

My next task is to sanboot the windows machine over the infiniband connection.

Have recent (built from recent source version of ipxe) ipxe does not recognise the infiniband connection during boot

net1 (connected port) shows : (typing this from smartphone picture of screen)
Using mt25210 on PCI04:00.0 (closed)
Link Down TX:0 TXE:0 RX:0 RXE:4
Status : Initialising ( ipxe.org/1a136101)
RXE 4 x "Operation cancelled (ipxe.org/0b1360a0)"
The remaining two connections also show link down (1x infiniband with no cable) and ethernet (with cable connected & working normally) that was working with ipxe prior to installing infiniband card)

Any suggestions on what I can do next to debug this? I have tried the suggestion of killall -HUP opensm without luck (using opensm 3.3.15 on linux Ubuntu 12.04). It seems to be scanning fabric every 10 secs reporting 0x02 -> SUBNET UP in log..
