gianfar: Fix typo bug introduced by move to udp_hdr()

2007-06-29T05:12:04+00:00

In commit 4bedb45203eab92a87b4c863fe2d0cded633427f both the udp and tcp cases where changed to use udp_hdr() instead of leaving the tcp case alone and fixing with tcp_hdr(). This ended up causing random behavior with TCP connections because of looking for tcp_hdr()->check in the wrong place. Signed-off-by: Kumar Gala

network drivers: eliminate unneeded kill_vid code

2007-06-03T15:44:20+00:00

Many drivers had code that did kill_vid, but they weren't doing vlan filtering. With new API the stub is unneeded unless device sets NETIF_F_HW_VLAN_FILTER. Bad habit: I couldn't resist fixing a couple of nearby style things in acenic, and forcedeth. Signed-off-by: Stephen Hemminger Signed-off-by: Jeff Garzik

gianfar: Add I/O barriers when touching buffer descriptor ownership.

2007-05-18T00:43:15+00:00

The hardware must not see that is given ownership of a buffer until it is completely written, and when the driver receives ownership of a buffer, it must ensure that any other reads to the buffer reflect its final state. Thus, I/O barriers are added where required. Without this patch, I have observed GCC reordering the setting of bdp->length and bdp->status in gfar_new_skb. Hardware reordering was also theoretically possible. Signed-off-by: Scott Wood Signed-off-by: Jeff Garzik

[SK_BUFF]: Introduce skb_network_header_len

2007-04-26T05:26:19+00:00

For the common sequence "skb->h.raw - skb->nh.raw", similar to skb->mac_len, that is precalculated tho, don't think we need to bloat skb with one more member, so just use this new helper, reducing the number of non-skbuff.h references to the layer headers even more.

[GIANFAR]: Fix compile error in latest git

[VLAN]: Avoid a 4-order allocation.

2007-03-03T04:44:51+00:00

This patch splits the vlan_group struct into a multi-allocated struct. On x86_64, the size of the original struct is a little more than 32KB, causing a 4-order allocation, which is prune to problems caused by buddy-system external fragmentation conditions. I couldn't just use vmalloc() because vfree() cannot be called in the softirq context of the RCU callback. Signed-off-by: Dan Aloni Acked-by: Jeff Garzik Signed-off-by: David S. Miller
