Subject: [dpdk-dev] [PATCH] net/ixgbe: fix VF Rx mode if allmulticast is disabled
Date: Thu, 4 May 2017 17:54:40 +0800 [thread overview]
Message-ID: <1493891680-39384-1-git-send-email-wei.dai@intel.com> (raw)
Some customers find that 82599 NIC DPDK VF PMD can't receive any
broadcast packets when it is bound to igb_uio in the first time
to run a DPDK application like testpmd. But when the application
is quited and run again, the DPDK VF PMD can receive broadcast
packets again. The associated PF is run by kernel driver when
the VF is driven by DPDK PMD.
When patch fixes this issue.
Fixes: 260e2e22e26f ("net/ixgbe/base: move multicast mode update")
Fixes: 72dec9e37a84 ("ixgbe: support multicast promiscuous mode on VF")
