virtio-net: Use virtio_config_val() for retrieving config

2011-11-02T01:10:58+00:00

This patch modifies virtio-net to use virtio_config_val() instead
of a 'if(virtio_has_feature()) vdev->config->get()' construct to retrieve
optional values from the config space.

virtio_net: fix truesize underestimation

2011-10-21T06:53:00+00:00

We must account in skb->truesize, the size of the fragments, not the
used part of them.

Doing this work is important to avoid unexpected OOM situations.

virtio_net: Clean up set_skb_frag()

2011-10-20T08:53:56+00:00

Remove manual initialization in set_skb_frag, and instead
use __skb_fill_page_desc() to do the same. Patch tested
on net-next.

net: add skb frag size accessors

2011-10-19T07:10:46+00:00

To ease skb->truesize sanitization, its better to be able to localize
all references to skb frags size.

Define accessors : skb_frag_size() to fetch frag size, and
skb_frag_size_{set|add|sub}() to manipulate it.

virtio-net: Verify page list size before fitting into skb

2011-10-06T19:39:40+00:00

This patch verifies that the length of a buffer stored in a linked list
of pages is small enough to fit into a skb.

If the size is larger than a max size of a skb, it means that we shouldn't
go ahead building skbs anyway since we won't be able to send the buffer as
the user requested.

net: introduce IFF_UNICAST_FLT private flag

2011-08-18T03:21:27+00:00

Use IFF_UNICAST_FTL to find out if driver handles unicast address
filtering. In case it does not, promisc mode is entered.

Patch also fixes following drivers:
stmmac, niu: support uc filtering and yet it propagated
	ndo_set_multicast_list
bna, benet, pxa168_eth, ks8851, ks8851_mll, ksz884x : has set
	ndo_set_rx_mode but do not support uc filtering

virtio_net: Fix panic in virtnet_remove

2011-07-22T04:29:34+00:00

Fix a panic in virtnet_remove. unregister_netdev has already
freed up the netdev (and virtnet_info) due to dev->destructor
being set, while virtnet_info is still required. Remove
virtnet_free altogether, and move the freeing of the per-cpu
statistics from virtnet_free to virtnet_remove.

Tested patch below.
