* sfc: Call netif_napi_add() before registering our interrupt handlerBen Hutchings2009-04-011-4/+3
| | | | | | | | | | | If we use a shared legacy IRQ then our interrupt handler may be called as soon as it is registered even though IRQs are disabled on the NIC. Now that the legacy interrupt handler also checks for event delivery, it may decide to schedule polling in this case. Ensure that the NAPI context is valid but disabled at this point.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In rare cases, reading the legacy interrupt status register can acknowledge an event queue whose attention flag has not yet been set in the register. Until we service this event queue it will not generate any more interrupts. Therefore, as a secondary check, poll the next slot in each active event queue whose flag is not set.

As GRO has a compatible external interface to LRO this is a very straightforward replacement. Everything should appear identical to the user except that the offload is now controlled by the GRO ethtool option instead of LRO. I've kept the lro module parameter as is since that's for compatibility only. I have eliminated efx_rx_mk_skb as the GRO layer can take care of all packets regardless of whether GRO is enabled or not. So the only case where we don't call GRO is if the packet checksum is absent. This is to keep the behaviour changes of the patch to a minimum.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following the removal of the unused struct net_device * parameter from the NAPI functions named *netif_rx_* in commit 908a7a1, they are exactly equivalent to the corresponding *napi_* functions and are therefore redundant.

| | | | | | | | | | | | | | | | | | | | pci_disable_device() disables many features, like MSI-X, which we never reenable in efx_reset(). Further, calls to pci_enable_device() and pci_disable_device() must be matched since the nesting count was introduced, so switch to using pci_clear_master() instead.
