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: dont allow bad hardware address from ROMStephen Hemminger
Sometimes boards don't reset properly, and the address read out of the EEPROM is zero. Stop the insanity before the device gets registered. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
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.

2006-06-08[PATCH] skge: use workq for PHY handlingStephen Hemminger
Since accessing the PHY can take 100's of usecs, use a work queue to allow spinning in outside of soft/hard irq. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
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
Skge driver always causes bad checksums on big-endian. The checksum in the receive control block was being swapped when it doesn't need to be. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-05-20[PATCH] Subjec: sky2, skge: correct PCI id for DGE-560TStephen Hemminger
The Dlink DGE-560T uses Yukon2 chipset so it needs sky2 driver; and the DGE-530T uses Yukon1 so it uses skge driver. Bug: http://bugzilla.kernel.org/show_bug.cgi?id=6544 Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

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: rx_reuse called twiceStephen Hemminger
In the error case we call skge_rx_reuse twice. This is harmless but unnecessary. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
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
The SysKonnect Genesis and Yukon chip sets have restrictions on the possible control block area. The memory needs to not cross 4 Gig boundary, and it needs to be 8 byte aligned. This patch checks and fails to bring the device up if region is unacceptable. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] skge: use auto masking of irqsStephen Hemminger
Improve performance of skge driver by not touching irq mask register as much. Since the interrupt source auto-masks, the driver can just leave it disabled until the end of the soft irq. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] skge: use NAPI for tx cleanup.Stephen Hemminger

2006-02-17[PATCH] skge: speed settingStephen Hemminger

2006-01-17[PATCH] skge: fix dma mask setup.Stephen Hemminger
There are a couple of problems in the DMA setup code for skge. * In the 64 bit case, it doesn't set the consistent mask. * In the 32 bit case, the error check is backwards!

2005-12-24[PATCH] skge: handle out of memory on MTU size changesStephen Hemminger
Changing the MTU size causes the receiver to have to reallocate buffers. If this allocation fails, then we need to return an error, and take the device offline.

If using UDP over VLAN, with the skge driver there is a possibility of generating an incorrect checksum.
