Subject: [DPDK/ethdev Bug 1629] Packets are not sent by the 1 GbE/10 GbE SR-IOV driver when the source MAC is not the MAC assigned to the VF NIC

Bug ID: 1629
Summary: Packets are not sent by the 1 GbE/10 GbE SR-IOV driver
when the source MAC is not the MAC assigned to the VF
NIC
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: nandinipersad361@gmail.com
Target Milestone: ---
The 1 GbE/10 GbE SR-IOV driver can only send packets when the Ethernet header’s
source MAC address is the same as that of the VF NIC. The reason for this is
that the Linux ixgbe driver module in the host OS has its anti-spoofing feature
enabled.
Implication:
Packets sent using the 1 GbE/10 GbE SR-IOV driver must have the source MAC
address correctly set to that of the VF NIC. Packets with other source address
values are dropped by the NIC if the application attempts to transmit them.
Resolution/Workaround:
Configure the Ethernet source address in each packet to match that of the VF
NIC.
Affected Environment/Platform:
All.
Driver/Module:
1 GbE/10 GbE VF Poll Mode Driver (PMD).
