[PATCH v2] virtio-net: free bufs correctly on invalid packet length
When a packet with invalid length arrives, ensure that the packet
is freed correctly if mergeable packet buffers and big packets
(GUEST_TSO4) are both enabled.

[PATCH] virtio_net: fix PAGE_SIZE > 64k
I don't have any guests with PAGE_SIZE > 64k but the
code seems to be clearly broken in that case
as PAGE_SIZE / MERGEABLE_BUFFER_ALIGN will need
more than 8 bit and so the code in mergeable_ctx_to_buf_address
does not give us the actual true size.

aliases not working!!
Can someone tell me what has to happen to get
the aliases working in samba?
Below is an earlier posting.
Thanks!!
Does anyone have aliases working correctly?
Suppose I am moving the samba to one server to another, say VIPER

[PATCH net-next] virtio-net: fix build error when CONFIG_AVERAGE is not enabled
Commit ab7db91705e9 ("virtio-net: auto-tune mergeable rx buffer size for
improved performance") introduced a virtio-net dependency on EWMA.
The inclusion of EWMA is controlled by CONFIG_AVERAGE. Fix build error
when CONFIG_AVERAGE is not enabled by adding select AVERAGE to
virtio-net's Kconfig entry.
Build failure reported using config make ARCH=s390 defconfig.

Problems Joining an ADS domain
We are having problems joining onto our 2003 server domain. This is
strange in that other linux clients on our network are NOT having
problems.
It appears that the domain will not allow new linux machines to join the
domain, even when allowing existing machines that have the exact same
configuration, to authenticate from the domain.
In order to test this I have taken a stripped down debian box

[PATCH net-next 1/3] net: allow > 0 order atomic page alloc in skb_page_frag_refill
skb_page_frag_refill currently permits only order-0 page allocs
unless GFP_WAIT is used. Change skb_page_frag_refill to attempt
higher-order page allocations whether or not GFP_WAIT is used. If
memory cannot be allocated, the allocator will fall back to
successively smaller page allocs (down to order-0 page allocs).
This change brings skb_page_frag_refill in line with the existing
page allocation

[PATCH net-next V3 1/2] net: introduce skb_coalesce_rx_frag()
Sometimes we need to coalesce the rx frags to avoid frag list. One example is
virtio-net driver which tries to use small frags for both MTU sized packet and
GSO packet. So this patch introduce skb_coalesce_rx_frag() to do this.
