2006-09-25[PATCH] skge: fiber supportStephen Hemminger
Add support for older fiber versions of the SysKonnect board. These chipsets use an internal PHY so they require special handling. The older sk98lin driver already supported these Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-09-06[PATCH] skge: use NAPI for transmit completeStephen Hemminger
The skge driver has much better performance if transmit done is handled in NAPI softirq. Change from doing transmit locking in driver (LLTX) and use device lock. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-09-06[PATCH] skge: irq lock raceStephen Hemminger
The driver needs to access the IRQ status inside of lock to avoid races with other places changing IRQ mask etc. This may be related to some of the SMP bugs reported against skge in kernel bugzilla. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-06-23[NET]: Avoid allocating skb in skb_padHerbert Xu
First of all it is unnecessary to allocate a new skb in skb_pad since the existing one is not shared. More importantly, our hard_start_xmit interface does not allow a new skb to be allocated since that breaks requeueing. This patch uses pskb_expand_head to expand the existing skb and linearize it if needed. Actually, someone should sift through every instance of skb_pad on a non-linear skb as they do not fit the reasons why this was originally created. Incidentally, this fixes a minor bug when the skb is cloned (tcpdump, TCP, etc.). As it is skb_pad will simply write over a cloned skb. Because of the position of the write it is unlikely to cause problems but still it's best if we don't do it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2006-06-08[PATCH] skge: transmit complete via IRQ not NAPIStephen Hemminger
The transmit side code has a number of ring problems that caused some of the Bugzilla reports. Rather than trying to fix the details, it is safer to rewrite the code that handles transmit completion and freeing.

2006-05-20[PATCH] skge: don't allow transmit ring to be too smallStephen Hemminger
The driver will get stuck (permanent transmit timeout), if the transmit ring size is set too small. It needs to have enough ring elements to hold one maximum size transmit. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-05-20[PATCH] skge: bad checksums on big-endian platformsStephen Hemminger

2006-03-23[PATCH] skge: compute available ring buffersStephen Hemminger
Don't need to keep track of available buffers, it is simpler to just compute the value (ala e1000). Don't need tes on link up because should always have available buffers then. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-23[PATCH] skge: dont free skb until multi-part transmit completeStephen Hemminger
Don't free transmit buffers until the whole set of transmit descriptors has been marked as done. Otherwise, we risk freeing a skb before the whole transmit is done. This changes the transmit completion handling from incremental to a two pass algorithm. First pass scans and records the start of the last done descriptor, second cleans up until that point.

2006-03-23[PATCH] skge: dont use dev_alloc_skb for rx buffsStephen Hemminger
The skge driver was using dev_alloc_skb which reserves space for the Ethernet header. This unnecessary and it should just use alloc_skb, also by using GFP_KERNEL during startup it won't run into problems when a user asks for a huge ring size or mtu and potentially drains the reserved atomic pool.

2006-03-21[PATCH] skge: check the allocation of ring bufferStephen Hemminger

2006-03-21[PATCH] skge: use auto masking of irqsStephen Hemminger
