Comment 20 for bug 1529815

The DHCP Relay issue still has not been resolved.
The issue was DHCP Offer packets that being sent from the DHCP server are not reaching the client.

Setup:
DHCP Client: IB Side Ubuntu OS with ConnectX3 FW ver 2.35.5000, Mellanox OFED 3.2-1.0.1
DHCP Server: ETH Side Win2012 R2 with ConnectX3 FW ver 2.35.5000, WinOF 5.10
SX GW, MLNX_OS ver 3.4.3002

Looking at the traffic capture I can see packets are coming from the Windows server towards the switch, but never leaving it.
Please refer to the following traffic capture files attached to the case:
Ibdump_dhcp – capture of ib0
Dhcp.pcap – port mirroring of the ETH port connected to the Windows
Dhcp_win2012 - wireshark capture of the windows dhcp server

Setup details is mentioned & marked above.

Setup:
IB Side: DHCP Client Ubunutu 14.04, OFED 3.2-1.0.1.1, CX3 2.35.5000 (10.7.55.193)
ETH Side: DHCP Server Win2012 R2, WinOF 5.10, CX3 2.35.5000 (10.7.55.190)
SX1036 GW: MLNX_OS ver 3.4.3002
