Some of the opcodes don't use in, out or both mboxes. In such cases, the mbox address is a reserved field and FW expects it to be zero. Signed-off-by:

The mlx5 driver calls ida_pre_get() in a loop for no readily apparent reason. The driver uses ida_simple_get() which will call ida_pre_get() by itself and there's no need to use ida_pre_get() unless using ida_get_new(). Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2018-03-19 This series contains updates to i40e and i40evf only. Alex fixes a potential deadlock in the configure_clsflower function in i40evf, where we exit with the "IN_CRITICAL_TASK" bit set while notifying the PF of flower filters. Jan fixed an issue where it was possible to set a mode that is not allowed which resulted in link being down, so fixed the parity between i40e_set_link_ksettings() and i40e_get_link_ksettings(). Patryk fixes a bug where a backplane device was allowing the setting of link settings, which is not allowed. Shiraz fixes a crash when entering S3 because the client interface was freeing the MSIx vectors while they are still in use. Jake fixes up a function header comment to document a newly added parameter. Also cleaned up flags that were never used. Doug fixes the incorrect return type for i40e_aq_add_cloud_filters(). ==================== Signed-off-by: -

The i40e_set_link_ksettings and i40e_get_link_ksettings use different codepaths to check available and supported advertisement modes. This creates scenarios where it's possible to set a mode that's not allowed, resulting in a link down. Fix setting advertisement in i40e_set_link_ksettings by calling i40e_get_link_ksettings to check what modes are allowed. Signed-off-by:

While doing some code review I noticed that we can get into a state where we exit with the "IN_CRITICAL_TASK" bit set while notifying the PF of flower filters. This patch is meant to address that plus tweak the ordering of the while loop waiting on it slightly so that we don't wait an extra period after we have failed for the last time. Signed-off-by:

Andrew Lunn says: ==================== Automatic PHY interrupts Now that the mv88e6xxx driver either installs in interrupt handler, or polls for interrupts, it is possible to always handle PHY interrupts, rather than have phylib perform the polling. This speeds up detection of link changes and reduces the load on the MDIO bus, which is beneficial for PTP. ==================== Signed-off-by: -
Andrew Lunn authored
When registering an MDIO bus, it is possible to pass an array of interrupts, one per address on the bus. phylib will then associate the interrupt to the PHY device, if no other interrupt is provided. Some of the global2 interrupts are PHY interrupts. Place them into the MDIO bus structure. Signed-off-by:

Andrew Lunn authored
With the recent change to polling for interrupts, it is important that the number of global 1 interrupts is listed. Without it, the driver requests an interrupt domain for zero interrupts, which returns EINVAL, and the probe fails. Add two missing entries. Signed-off-by:

Stefano Brivio says: ==================== selftests: pmtu: Add further vti/vti6 MTU and PMTU tests Patches 5/10 to 10/10 add tests to verify default MTU assignment for vti4 and vti6 interfaces, to check that MTU values set on new link and link changes are properly taken and validated, and to verify PMTU exceptions on vti4 interfaces. Patch 1/10 reverses function return codes as suggested by David Ahern. Patch 2/10 fixes the helper to fetch exceptions MTU to run in the passed namespace. Patches 3/10 and 4/10 are preparation work to make it easier to introduce those tests. v2: Reverse return codes, and make output prettier in 4/9 by using padded printf, test descriptions and buffered error strings.

This test checks that PMTU exceptions are created only when needed on IPv4 routes with vti and xfrm, and their PMTU value is checked as well. We can't adopt the same approach as test_pmtu_vti6_exception() here, because on IPv4 administrative MTU changes won't be reflected directly on PMTU. Signed-off-by:

Introduce list of tests and their descriptions, and loop on it in main body. Tests will now just take care of calling setup with a list of "units" they need, and return 0 on success, 1 on failure, 2 if the test had to be skipped. Main script body will take care of displaying results and cleaning up after every test. Introduce guard variable so that we don't clean up twice in case of interrupts or unexpected failures. The pmtu_vti6_exception test can now run its third step even if the previous one failed, as we can return values from it. Also introduce support to display test descriptions, and display aligned OK/FAIL/SKIP test outcomes. Buffer error strings so that in case of failure we can display them right under the outcome for each test. Signed-off-by:

David suggests it's more intuitive to return non-zero on failures, and zero on success. No need to introduce tail 'return 0' in functions, they will return the exit code of the last command anyway. Suggested-by:

Thomas Falcon says: ==================== ibmvnic: Update TX pool and TX routines This patch restructures the TX pool data structure and provides a separate TX pool array for TSO transmissions. This is already used in some way due to our unique DMA situation, namely that we cannot use single DMA mappings for packet data. Previously, both buffer arrays used the same pool entry. This restructuring allows for some additional cleanup in the driver code, especially in some places in the device transmit routine. In addition, it allows us to more easily track the consumer and producer indexes of a particular pool. This has been further improved by better tracking of in-use buffers to prevent possible data corruption in case an invalid buffer entry is used. v5: Fix bisectability mistake in the first patch. Removed TSO-specific data in a later patch when it is no longer used. v4: Fix error in 7th patch that causes an oops by using the older fixed value for number of buffers instead of the respective field in the tx pool data structure v3: Forgot to update TX pool cleaning function to handle new data structures. Included 7th patch for that. v2: Fix typo in 3/6 commit subject line ==================== Signed-off-by: -

Improve TX pool buffer accounting to prevent the producer index from overruning the consumer. First, set the next free index to an invalid value if it is in use. If next buffer to be consumed is in use, drop the packet. Finally, if the transmit fails for some other reason, roll back the consumer index and set the free map entry to its original value. This should also be done if the DMA map fails. Signed-off-by:

Update TX and TX completion routines to account for TX pool restructuring. TX routine first chooses the pool depending on whether a packet is GSO or not, then uses it accordingly. For the completion routine to know which pool it needs to use, set the most significant bit of the correlator index to one if the packet uses the TSO pool. On completion, unset the bit and use the correlator index to release the buffer pool entry. Signed-off-by:
