* [PATCH] 64bit resource: fix up printks for resources in networks driversGreg Kroah-Hartman2006-06-27
| | | | | | | | | | This is needed if we wish to change the size of the resource structures. Based on an original patch from Vivek Goyal <vgoyal@in.ibm.com> Cc: Vivek Goyal <vgoyal@in.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [NET]: Avoid allocating skb in skb_padHerbert Xu2006-06-23
| | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] skge: dont allow bad hardware address from ROMStephen Hemminger2006-06-08
| | | | | | | | 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>
* [PATCH] skge: transmit complete via IRQ not NAPIStephen Hemminger2006-06-08
| | | | | | | | | 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.

* [PATCH] skge: use workq for PHY handlingStephen Hemminger2006-06-08

* [PATCH] skge: don't allow transmit ring to be too smallStephen Hemminger2006-05-20
| | | | | | | | | 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>
* [PATCH] skge: bad checksums on big-endian platformsStephen Hemminger2006-05-20

* [PATCH] skge: compute available ring buffersStephen Hemminger2006-03-23
| | | | | | | | | 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>
* [PATCH] skge: dont free skb until multi-part transmit completeStephen Hemminger2006-03-23
| | | | | | | | | | | | | 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.

* [PATCH] skge: dont use dev_alloc_skb for rx buffsStephen Hemminger2006-03-23
| | | | | | | | | | | 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.

* [PATCH] skge: use auto masking of irqsStephen Hemminger2006-03-21
