2014-09-19bnx2x: Add a fallback multi-function mode NPAR1.5Yuval Mintz
When using new Multi-function modes it's possible that due to incompatible configuration management FW will fallback into an existing mode. Notice that at the moment this fallback is exactly the same as the already existing switch-independent multi-function mode, but we still use existing infrastructure to hold this information [in case some small differences will arise in the future].

Rearrange macros to query for storage-only modes in different MF environment. Improves the readibility and maintainability of the code. E.g.: - if (IS_MF_STORAGE_SD(bp) || IS_MF_FCOE_AFEX(bp)) + if (IS_MF_STORAGE_ONLY(bp)) In addition, this removes the need for bnx2x_is_valid_ether_addr().

2014-09-02bnx2x: Configure device endianity on driver load and reset endianity on removal.Manish Chopra
Some hosts can be both little and big endian. In certain scenarios a big endian kernel can kexec a little endian kernel. This patch fixes this case from both ends: 1) Return endianity to original values on shutdown (in case little endian kernel boots after we shutdown). 2) Do not rely on HW reset values when loading driver in little endian kernel but configure them explicitly (in case previous kernel was big endian and did not reset the HW).

Trying to disable sriov when VFs are assigned may lead to all kinds of problems. This patch unifies the call in the driver to pci_disable_sriov() and prevents them if some of the PF's child VFs are marked as assigned. [Notice this is a bad scenario either way; User should not reach a point where the OS tries to disable SRIOV when a VF is assigned - but currently there's no way of preventing the user from doing so, and the ill-effect for the driver is smaller this way] Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: Ariel Elior <Ariel.Elior@qlogic.com> Signed-off-by: David S.

2014-08-21bnx2x: Revert UNDI flushing mechanismYuval Mintz
Commit 91ebb929b6f8 ("bnx2x: Add support for Multi-Function UNDI") [which was later supposedly fixed by de682941eef3 ("bnx2x: Fix UNDI driver unload")] introduced a bug in which in some [yet-to-be-determined] scenarios the alternative flushing mechanism which was to guarantee the Rx buffers are empty before resetting them during device probe will fail. If this happens, when device will be loaded once more a fatal attention will occur; Since this most likely happens in boot from SAN scenarios, the machine will fail to load. Notice this may occur not only in the 'Multi-Function' scenario but in the regular scenario as well, i.e., this introduced a regression in the driver's ability to perform boot from SAN. The patch reverts the mechanism and applies the old scheme to multi-function devices as well as to single-function devices.

There are linux distributions where the inbox bnx2x driver contains SRIOV support but doesn't contain the changes introduced in b9871bcf "bnx2x: VF RSS support - PF side". A VF in a VM running that distribution over a new hypervisor will access incorrect addresses when trying to transmit packets, causing an attention in the hypervisor and making that VF inactive until FLRed. The driver in the VM has to ne upgraded [no real way to overcome this], but due to the HW attention currently arising upgrading the driver in the VM would not suffice [since the VF needs also be FLRed if the previous driver was already loaded]. This patch causes the PF to fail the acquire message from a VF running an old problematic driver; The VF will then gracefully fail it's probe preventing the HW attention [and allow clean upgrade of driver in VM].

2014-06-12bnx2x: Enlarge the dorq threshold for VFsAriel Elior
A malicious VF might try to starve the other VFs & PF by creating contineous doorbell floods. In order to negate this, HW has a threshold of doorbells per client, which will stop the client doorbells from arriving if crossed. The threshold currently configured for VFs is too low - under extreme traffic scenarios, it's possible for a VF to reach the threshold and thus for its fastpath to stop working.

2014-06-03bnx2x: Fix kernel crash and data miscompare after EEH recoverywenxiong@linux.vnet.ibm.com
A rmb() is required to ensure that the CQE is not read before it is written by the adapter DMA. PCI ordering rules will make sure the other fields are written before the marker at the end of struct eth_fast_path_rx_cqe but without rmb() a weakly ordered processor can process stale data. Without the barrier we have observed various crashes including bnx2x_tpa_start being called on queues not stopped (resulting in message start of bin not in stop) and NULL pointer exceptions from bnx2x_rx_int.

git://git.kernel.org/pub/scm/linux/kernel/git/bwh/net-next Ben Hutchings says: ==================== Pull request: Fixes for new ethtool RSS commands This addresses several problems I previously identified with the new ETHTOOL_{G,S}RSSH commands: 1. Missing validation of reserved parameters 2. Vague documentation 3. Use of unnamed magic number 4. No consolidation with existing driver operations I don't currently have access to suitable network hardware, but have tested these changes with a dummy driver that can support various combinations of operations and sizes, together with (a) Debian's ethtool 3.13 (b) ethtool 3.14 with the submitted patch to use ETHTOOL_{G,S}RSSH and minor adjustment for fixes 1 and 3. v2: Update RSS operations in vmxnet3 too ==================== Signed-off-by: David S.
