2017-05-31i40evf: fix merge error in older patchJesse Brandeburg
This patch fixes a missing line that was missed while merging, which results in a driver feature in the VF not working to enable RSS as a negotiated feature.

2017-05-30nfp: don't wait for resources indefinitelyJakub Kicinski
There is currently no timeout to the resource and lock acquiring loops. We printed warnings and depended on user sending a signal to the waiting process to stop the waiting. This doesn't work very well when wait happens out of a work queue. The simplest example of that is PCI probe. When user loads the module and card is in a broken state modprobe will wait forever and signals sent to it will not actually reach the probing thread. Make sure all wait loops have a time out.

2017-05-30nfp: support long reads and writes with the cpp helpersJakub Kicinski
nfp_cpp_{read,write}() helpers perform device memory mapping (setting the PCIe -> NOC translation BARs) and accessing it. They, however, currently implicitly expect that the length of entire operation will fit in one BAR translation window. There is a number of 16MB windows available, and we don't really need to access such large areas today. If the user, however, manages to trick the driver into making a big mapping (e.g. by providing a huge fake FW file), the driver will print a warning saying "No suitable BAR found for request" and a stack trace - which most users find concerning. To be future-proof and not scare users with warnings, make the nfp_cpp_{read,write}() helpers do accesses chunk by chunk if the area size is large. Set the notion of "large" to 2MB, which is the size of the smallest BAR window. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-05-30nfp: only try to get to PCIe ctrl memory if BARs are wide enoughJakub Kicinski

2017-05-30nfp: don't set aux pointers if ioremap failedJakub Kicinski
If ioremap of PCIe ctrl memory failed we can still get to it through PCI config space, therefore we allow ioremap() to fail. When if fails, however, we must leave all the IOMEM pointers as NULL. Currently we would calculate csr and em pointers, adding offsets to the potential NULL value and therefore making the NULL-checks throughout the code ineffective.

PCI subsystem has support for drivers limiting the number of VFs available below what the IOV capability claims. Make use of it. While at it remove the #ifdef/#endif on CONFIG_PCI_IOV, it was there to avoid unnecessary warnings in case device read failed but kernel doesn't have SR-IOV support anyway. Device reads should not fail. Note that we still need the driver-internal check for the case where max VFs is 0 since PCI subsystem treats 0 as limit not set.
