about sr-iov
...pter. I
thought BIOS got some problem to assign right memory for VFs and I tried to
pass *pci=assign-busses* to kernel, but it still failed. Does the 82576 card
SR-IOV need a BIOS enable and a *REBOOT* to make the function active? Can
anyone just give me some ideas? Thanks.
Best Regards

[PATCH net 0/2] add checking sq is full inside xdp xmit
If the queue of xdp xmit is not an independent queue, then when the xdp
xmit used all the desc, the xmit from the __dev_queue_xmit() may encounter
the following error.
net ens4: Unexpected TXQ (0) queue failure: -28
This patch adds a check whether sq is full in XDP Xmit.
Thanks.
Xuan Zhuo (2):
virtio_net: separate the logic of checking whether sq is full
virtio_net: add checking sq is full inside xdp xmit
