There is no need for this to be unsigned long; make it unsigned int. It does need a line in kernel-doc, so add that. Signed-off-by:

Currently TX completions do not count towards the NAPI budget. This means a continuous stream of TX completions can cause the polling function to loop indefinitely with scheduling disabled. To avoid this, follow the common practice of reporting the budget spent after processing one ring-full of TX completions. Signed-off-by:

Siena has two problems with legacy interrupts: 1. There is no synchronisation between the ISR read completion, and the interrupt deassert message. 2. A downstream read at the "wrong" moment can return 0, and suppress generating the next interrupt. Falcon should suffer from both of these, and it appears it does. Enable EFX_WORKAROUND_15783 on Falcon as well. Also, when we see queues == 0, ensure we always schedule or rearm every event queue. Signed-off-by:

The aim of this code was to avoid a spurious XGMII fault over a MAC reconfigure. It's less relevant now that the PHY reconfigure isn't called from the MAC reconfigure. After applying this patch, our link stress test passed 48 hours of testing without ever resetting the PHY. Signed-off-by:

'Fatal' errors set an interrupt flag associated with a specific event queue; only read the syndrome vector if we see that queue's flag set (legacy interrupts) or in the interrupt handler for that queue (MSI). Do not ignore an interrupt if the fatal error flag is set but specific error flags are all zero. Even if we don't schedule a reset, we must respect the queue mask and rearm the appropriate event queues. Signed-off-by:

Siena has a separate SRAM bank for each port. On single-port boards these can be merged together, so each port has an interrupt flag for parity errors in the other port's SRAM. Currently we do not enable such merging and should mask this interrupt source. Signed-off-by:

The recently introduced bridge mulitcast port group list was only partially using RCU correctly. It was missing rcu_dereference() and missing the necessary barrier on deletion. The code should have used one of the standard list methods (list or hlist) instead of open coding a RCU based link list. Signed-off-by:

This patch is an alternative to similar patch provided by Joe Perches. Substitute DPRINTK macro for e_<level> that uses netdev_<level> and dev_<level> similar to e1000e. - Convert printk to pr_<level> where applicable. - Use common #define pr_fmt for the driver. - Use dev_<level> for displaying text in parts of the driver where the interface name is not assigned (like e1000_param.c). - Better align test with the new macros.

This patch makes it so that igb now uses the DMA API functions instead of the PCI API functions. To do this the pci_dev pointer that was in the rings has been replaced with a device pointer, and as a result all references to [tr]x_ring->pdev have been replaced with [tr]x_ring->dev. This patch is based of of work originally done by Nicholas Nunley. Signed-off-by:
