2012-07-18net: ftgmac100/ftmac100: dont pull too much dataEric Dumazet2-6/+14
Drivers should pull only ethernet header from page frag to skb->head. Pulling 64 bytes is too much for TCP (without options) on IPv4. However, it makes sense to pull all the frame if it fits the 128 bytes bloc allocated for skb->head, to free one page per small incoming frame.

2012-07-18ixgbe: Cleanup logic for MRQC and MTQC configurationAlexander Duyck1-50/+66
This change is meant to make the code much more readable for MTQC and MRQC configuration. The big change is that I simplified much of the logic so that we are essentially handling just 4 cases and their variants. In the cases where RSS is disabled we are actually just programming the RETA table with all 1s resulting in a single queue RSS. In the case of SR-IOV I am treating that as a subset of VMDq. This all results int he following configuration for the hardware: DCB En Dis VMDq En VMDQ/DCB VMDq/RSS Dis DCB/RSS RSS Cc: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Tested-by: Stephen Ko <stephen.s.ko@intel.com> Tested-by: Ross Brattain <ross.b.brattain@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2012-07-18ixgbe: Update the logic for ixgbe_cache_ring_dcb and DCB RSS configurationAlexander Duyck2-50/+42
This change cleans up some of the logic in an attempt to try and simplify things for how we are configuring DCB w/ RSS. In this patch I basically did 3 things. I updated the logic for getting the first register index. I applied the fact that all TCs get the same number of queues to simplify the looping logic in caching the DCB ring register. Finally I updated how we configure the RQTC register to match the fact that all TCs are assigned the same number of queues.

2012-07-18ixgbe: Move configuration of set_real_num_rx/tx_queues into openAlexander Duyck2-56/+38
It makes much more sense for us to configure the real number of Tx and Rx queues in the ixgbe_open call than it does in ixgbe_set_num_queues. By setting the number in ixgbe_open we can avoid a number of unecessary updates and only have to make the calls once.

2012-07-18ixgbe: Handle failures in the ixgbe_setup_rx/tx_resources callsAlexander Duyck1-4/+16
Previously we were exiting without cleaning up the memory internally on the ixgbe_setup_rx_resources and ixgbe_setup_tx_resources calls. Instead of forcing the caller to clean things up for us we should instead just unwind the rings and free the memory as we go. This way we can more gracefully clean up the rings in the event of an allocation failure.

When the link status changes on the PF we need to notify the VFs. In order to do this we should ping all of the VFs in order to trigger a link status change on them as well. This fixes issues in which the PF would reset, but the VF didn't because the NAK flag was not set in the VF mailbox.

2012-07-17sfc: Fix interface statistics running backwardBen Hutchings3-10/+28
Some interface statistics are computed in such a way that they can sometimes decrease (and even underflow). Since the computed value will never be greater than the true value, we fix this by only storing the computed value when it increases. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-07-17sfc: Disable VF queues during register self-testBen Hutchings5-60/+76
Currently VF queues and drivers may remain active during this test. This could cause memory corruption or spurious test failures. Therefore we reset the port/function before running these tests on Siena. On Falcon this doesn't work: we have to do some additional initialisation before some blocks will work again. So refactor the reset/register-test sequence into an efx_nic_type method so efx_selftest() doesn't have to consider such quirks. In the process, fix another minor bug: Siena does not have an 'invisible' reset and the self-test currently fails to push the PHY configuration after resetting. Passing RESET_TYPE_ALL to efx_reset_{down,up}() fixes this. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-07-17sfc: Use dev_kfree_skb() in efx_end_loopback()Ben Hutchings1-1/+1
Fix CID 102619 in the Coverity report on Linux. efx_end_loopback() iterates over an array of skb pointers of which some may be null (if efx_begin_loopback() failed). It should not use dev_kfree_skb_irq(), which requires non-null pointers. In practice this is safe because it does not run in interrupt context and therefore always ends up calling dev_kfree_skb(), which does allow null pointers. But we should make that explicit.

With some gcc versions & optimisations, the compiler will warn that 'depth' in efx_filter_insert_filter() may be used without being initialised, although this is not the case. This is related to inlining of efx_filter_search(), which only has one caller since commit 8db182f4a8a6e2dcb8b65905ea4af56210e65430 ('sfc: Remove now-unused filter function').

The interrupt registers accessed in ixgbevf are more similar to the igb style registers than they are to the ixgbe style registers.

Currently the VF driver is processing all of the transmits in interrupt context. This can be messy since the Rx is all handled in NAPI and this may result in interrupts being disabled.

For most cases the ixgbevf driver will only ever contain a single Tx and single Rx queue. In order to track that it makes more sense to use a pointer instead of using a bitmap which must be search in order to locate the ring on an adapter index.
