net: Allow netdevices to specify needed head/tailroom

2008-05-13T03:48:31+00:00

This patch adds needed_headroom/needed_tailroom members to struct
net_device and updates many places that allocate sbks to use them. Not
all of them can be converted though, and I'm sure I missed some (I
mostly grepped for LL_RESERVED_SPACE)

netpoll: zap_completion_queue: adjust skb->users counter

2008-03-20T23:07:27+00:00

zap_completion_queue() retrieves skbs from completion_queue where they have
zero skb->users counter.  Before dev_kfree_skb_any() it should be non-zero
yet, so it's increased now.

[NETPOLL]: Revert two bogus cleanups that broke netconsole.

2008-03-04T20:28:49+00:00

Based upon a report by Andrew Morton and code analysis done
by Jarek Poplawski.

This reverts 33f807ba0d9259e7c75c7a2ce8bd2787e5b540c7 ("[NETPOLL]:
Kill NETPOLL_RX_DROP, set but never tested.")  and
c7b6ea24b43afb5749cb704e143df19d70e23dea ("[NETPOLL]: Don't need
rx_flags.").

The rx_flags did get tested for zero vs. non-zero and therefore we do
need those tests and that code which sets NETPOLL_RX_DROP et al.

[ARP]: Introduce the arp_hdr_len helper.

2008-03-03T20:20:57+00:00

There are some place, that calculate the ARP header length. These
calculations are correct, but 
 a) some operate with "magic" constants,
 b) enlarge the code length (sometimes at the cost of coding style),
 c) are not informative from the first glance.

The proposal is to introduce a helper, that includes all the good
sides of these calculations.

[NETPOLL]: Don't need rx_flags.

2008-01-28T22:54:18+00:00

The rx_flags variable is redundant. Turning rx on/off is done
via setting the rx_np pointer.

[NETPOLL]: no need to store local_mac

2008-01-28T22:54:17+00:00

The local_mac is managed by the network device, no need to keep a
spare copy and all the management problems that could cause.
