The commit to convert to use the dev_pm_ops struct introduces a bug. The shutdown flag is not yet used because the hibernation on memory is done by using the freeze callback. Thanks to Vlad for having reported it. Reported-by:

Currently the ret variable is not used for anything other than receive the value of the t3_adapter_error(), which will always be 0, because the reset parameter is 0. Signed-off-by:

jhash is widely used in the kernel and because the functions are inlined, the cost in size is significant. Also, the new jhash functions are slightly larger than the previous ones so better un-inline. As a preparation step, the calls to the internal macros are replaced with the plain jhash function calls.

Calculating the BD entry using a modulus operation isn't optimal, especially inside the loop. This patch removes the modulus operations in favour of: i) simply checking for wrapping in the case of cur_rx ii) forcing num_tx to be a power of two and using it to mask out the entry from cur_tx The also prevents possible issues related overflow of the cur_rx and cur_tx counters.

update_ethoc_tx_stats doesn't need to return anything so make its return type void in order to avoid an unnecessary cast when the function is called. Signed-off-by:

MDIO read and write were checking whether a timeout had expired to determine whether to recheck the result of the MDIO operation. Under heavy CPU usage, however, it was possible for the timeout to expire before the routine got around to be able to check a second time even, thus erroneousy returning an -EBUSY. This patch changes the the MDIO IO routines to try up to five times to complete the operation before giving up, thus lessening the dependency on CPU load. This resolves a problem whereby a ping flood would keep the CPU so busy that the above problem would manifest itself; the MDIO command to check link status would fail and the interface would erroneously be shut down.

The old interrupt handling was incorrect in that it did not account for the fact that the interrupt source bits get set irregardless of whether or not their corresponding mask is set. This patch fixes that by masking off the source bits for masked interrupts. Furthermore, the handling of transmission events is moved to the NAPI polling handler alongside the reception handler, thus preventing a whole bunch of interrupts during heavy traffic. Signed-off-by:

An interrupt may occur between checking bd.stat and clearing the interrupt source register which would result in the packet going totally unnoticed as the interrupt will be missed. Double check bd.stat after clearing the interrupt source register to guard against such an occurrence. Signed-off-by:

Occasionally, it seems that some race is causing the interrupts to not be reenabled otherwise with the end result that networking just stops working. Enabling interrupts after calling napi_complete is more in line with what other drivers do. Signed-off-by:

This patch adds the ability to describe ethernet devices via a flattened device tree. As device tree remains an optional feature, these bits all need to be guarded by CONFIG_OF ifdefs. MAC address is settable via the device tree parameter "local-mac-address"; however, the selection of the phy id is limited to probing, for now. Signed-off-by:

The 5709 chip requires the BNX2_MISC_NEW_CORE_CTL_DMA_ENABLE bit to be cleared and polling for pending DMAs to complete before chip reset. Without this step, we've seen NMIs during repeated resets of the chip. Signed-off-by:

In kdump environment do not depend on reset_devices parameter to reset the device as the parameter may become obsolete. Instead use an adapter specific mechanism to determine if the device needs a reset. Driver maintains a count of number of pci functions probed and decrements the count when remove handler of that pci function is called. If the first probe, probe of function 0, detects the count as non zero then reset the device. Signed-off-by:

As David pointed out correctly, updates to af-specific attributes are currently not atomic. If multiple changes are requested and one of them fails, previous updates may have been applied already leaving the link behind in a undefined state. This patch splits the function parse_link_af() into two functions validate_link_af() and set_link_at(). validate_link_af() is placed to validate_linkmsg() check for errors as early as possible before any changes to the link have been made. set_link_af() is called to commit the changes later. This method is not fail proof, while it is currently sufficient to make set_link_af() inerrable and thus 100% atomic, the validation function method will not be able to detect all error scenarios in the future, there will likely always be errors depending on states which are f.e. not protected by rtnl_mutex and thus may change between validation and setting. Also, instead of silently ignoring unknown address families and config blocks for address families which did not register a set function the errors EAFNOSUPPORT respectively EOPNOSUPPORT are returned to avoid comitting 4 out of 5 update requests without notifying the user.
