* drivers/net: avoid some skb->ip_summed initializationsEric Dumazet2010-09-021-1/+1
| | | | | | | | | | | | | | | | | | | | fresh skbs have ip_summed set to CHECKSUM_NONE (0) We can avoid setting again skb->ip_summed to CHECKSUM_NONE in drivers. Introduce skb_checksum_none_assert() helper so that we keep this assertion documented in driver sources. Change most occurrences of : skb->ip_summed = CHECKSUM_NONE; by : skb_checksum_none_assert(skb); Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* cxgb4vf: do not use PCI resources before pci_enable_device()Kulikov Vasiliy2010-08-041-15/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | IRQ and resource[] may not have correct values until after PCI hotplug setup occurs at pci_enable_device() time. The semantic match that finds this problem is as follows: // <smpl> @@ identifier x; identifier request ~= "pci_request.*|pci_resource.*"; @@ ( * x->irq | * x->resource | * request(x, ...) ) ... *pci_enable_device(x) // </smpl> Signed-off-by: Kulikov Vasiliy <segooon@gmail.com> Signed-off-by: David S.

| | | | | | | | | Fix off-by-one error in checking for the end of the mailbox response delay array. We ended up walking off the end and, if we were unlucky, we'd end up pulling in a 0 and never terminate the mailbox response delay loop ...

| | | | | | | | | Fix up TX Queue Host Flow Control to cause an Egress Queue Status Update to be generated when we run out of TX Queue Descriptors. This will, in turn, allow us to restart a stopped TX Queue. Signed-off-by: Casey Leedom <leedom@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | We could use DEFINE_DMA_UNMAP_ADDR instead but using CONFIG_NEED_DMA_MAP_STATE is a simpler way to see if a platform does real DMA unmapping. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | Boundary Use correct shift factor for extracting the SGE DMA Ingress Padding Boundary. Was accidentally using the register field's shift which was close enough (4 instead of the propper value of 5) that it actually sort of worked for various packet sizes ...
