2018-08-24ixgbe: Be more careful when modifying MAC filtersAlexander Duyck1-1/+11
[ Upstream commit d14c780c11fbc10f66c43e7b64eefe87ca442bd3 ] This change makes it so that we are much more explicit about the ordering of updates to the receive address register (RAR) table. Prior to this patch I believe we may have been updating the table while entries were still active, or possibly allowing for reordering of things since we weren't explicitly flushing writes to either the lower or upper portion of the register prior to accessing the other half.

The ixgbe driver use the compile check to determine if it can send TLPs to Root Port with the Relaxed Ordering Attribute set, this is too inconvenient, now the new flag PCI_DEV_FLAGS_NO_RELAXED_ORDERING has been added to the kernel and we could check the bit4 in the PCIe Device Control register to determine whether we should use the Relaxed Ordering Attributes or not, so use this new way in the ixgbe driver.

2017-10-09Revert commit 1a8b6d76dc5b ("net:add one common config...")Ding Tianhong1-1/+1
The new flag PCI_DEV_FLAGS_NO_RELAXED_ORDERING has been added to indicate that Relaxed Ordering Attributes (RO) should not be used for Transaction Layer Packets (TLP) targeted toward these affected Root Port, it will clear the bit4 in the PCIe Device Control register, so the PCIe device drivers could query PCIe configuration space to determine if it can send TLPs to Root Port with the Relaxed Ordering Attributes set. With this new flag we don't need the config ARCH_WANT_RELAX_ORDER to control the Relaxed Ordering Attributes for the ixgbe drivers just like the commit 1a8b6d76dc5b ("net:add one common config...") did, so revert this commit.

2017-01-04ixgbe: Fix issues with EEPROM accessMark Rustad1-35/+62
There are two problems with EEPROM access. One is that it needs to hold the semaphore until the entire response is read or else the response can be corrupted by other firmware accesses. The second problem is that acquiring and releasing the semaphore is slow, so it should be taken and released once when multiple EEPROM accesses will be done. Both of these issues can be solved by adding a new function, ixgbe_hic_unlocked, to issue firmware commands that will assume that the caller has acquired the needed semaphore.

2016-04-25ixgbe: use BIT() macroJacob Keller1-15/+15
Several areas of ixgbe were written before widespread usage of the BIT(n) macro. With the impending release of GCC 6 and its associated new warnings, some usages such as (1 << 31) have been noted within the ixgbe driver source. Fix these wholesale and prevent future issues by simply using BIT macro instead of hand coded bit shifts. Also fix a few shifts that are shifting values into place by using the 'u' prefix to indicate unsigned. It doesn't strictly matter in these cases because we're not shifting by too large a value, but these are all unsigned values and should be indicated as such.

2015-12-12ixgbe: Simplify configuration of setting VLVF and VLVFBAlexander Duyck1-54/+34
This patch addresses several issues within the VLVF and VLVFB configuration First was the fact that code was overly complicated with multiple conditional paths depending on if we adding or removing and which bit we were going to add or remove. Instead of messing with all that I have simplified it by using (vid / 32) and (1 - vid / 32) to identify our register and the other vlvfb register. Second was the fact that we were likely leaking a few packets into the PF in cases where we were deleting an entry and the VFTA filter for that entry as the ordering was such that we deleted the pool and then the VLAN filter instead of the other way around. I have updated that by adding a check for no bits being set and if that occurs we clear things up in the proper order.

2014-12-05ixgbe: Add X550 support function pointersDon Skidmore1-3/+3
This patch extends the function pointer structure to include the new X550 class MAC types. This creates a new file ixgbe_x550.c that contains all of the new methods. Because of similarities to the X540 part in some cases we just use it's methods where they can be used without any modification. These exported functions are now defined in the new ixgbe_x540.h file.
