Only the 578xx adapters are capable of configuring UDP ports for the purpose of tunnelling - doing the same on 577xx might lead to a firmware assertion. We're already not claiming support for any related feature for such devices, but we also need to prevent the configuration of the UDP ports to the device in this case.

Until interface is up [and assuming ringparams weren't explicitly configured] when queried for the size of its rings bnx2x would claim they're the maximal size by default. That is incorrect as by default the maximal number of buffers would be equally divided between the various rx rings. This prevents the user from actually setting the number of elements on each rx ring to be of maximal size prior to transitioning the interface into up state. To fix this, make a rough estimation about the number of buffers. It wouldn't always be accurate, but it would be much better than current estimation and would allow users to increase number of buffers during early initialization of the interface.

Macro BNX2X_ALLOC_AND_SET(arr, lbl, func) calls kmalloc() to allocate memory, and jumps to label "lbl" if the allocation fails. Label "lbl" first cleans memory and then returns variable rc. Before calling the macro, the value of variable rc is 0. Because 0 means no error, the callers of bnx2x_init_firmware() may be misled. This patch fixes the bug, assigning "-ENOMEM" to rc before calling macro NX2X_ALLOC_AND_SET().

If the physical link is down and the VF virtual link is set to "enable", the current code does not always work. If the link is down but the cable is attached, the firmware returns LINK_SIGNAL instead of NO_LINK. The current code is treating LINK_SIGNAL as link up.

Current bgmac code initializes some DMA settings in the receive control register for some hardware and then immediately clears those settings. Not clearing those settings results in ~420Mbps *improvement* in throughput; this system can now receive frames at line-rate on Broadcom 5871x hardware compared to ~520Mbps today. I also tested a few other values but found there to be no discernible difference in CPU utilization even if burst size and prefetching values are different. On the hardware tested there was no need to keep the code that cleared all but bits 16-17, but since there is a wide variety of hardware that used this driver (I did not look at all hardware docs for hardware using this IP block), I find it wise to move this call up and clear bits just after reading the default value from the hardware rather than completely removing it. This is a good candidate for -stable >=3.14 since that is when the code that was supposed to improve performance (but did not) was introduced.
