In our documentation, we claim to use a 5-tuple key for Rx hash distribution of flows. The code however configures a key composed of all supported header fields. Update the Rx hash key to contain only the documented fields: {IP src, IP dst, IP nextproto, L4 src, L4 dst}, which was the original intention and makes most sense as a default.

Most Ethernet drivers don't enforce the MTU value as upper limit for ingress frames. We too support receiving frames larger than MTU, so allow that.

2018-06-09Merge tag 'staging-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/stagingLinus Torvalds15-29/+1519
Pull staging/IIO updates from Greg KH: "Here is the big staging and IIO driver update for 4.18-rc1. It was delayed as I wanted to make sure the final driver deletions did not cause any major merge issues, and all now looks good. There are a lot of patches here, just over 1000. The diffstat summary shows the major changes here: 1007 files changed, 16828 insertions(+), 227770 deletions(-) Because of this, we might be close to shrinking the overall kernel source code size for two releases in a row. There was loads of work in this release cycle, primarily: - tons of ks7010 driver cleanups - lots of mt7621 driver fixes and cleanups - most driver cleanups - wilc1000 fixes and cleanups - lots and lots of IIO driver cleanups and new additions - debugfs cleanups for all staging drivers - lots of other staging driver cleanups and fixes, the shortlog has the full details. but the big user-visable things here are the removal of 3 chunks of code: - ncpfs and ipx were removed on schedule, no one has cared about this code since it moved to staging last year, and if it needs to come back, it can be reverted. - lustre file system is removed. I've ranted at the lustre developers about once a year for the past 5 years, with no real forward progress at all to clean things up and get the code into the "real" part of the kernel. Given that the lustre developers continue to work on an external tree and try to port those changes to the in-kernel tree every once in a while, this whole thing really really is not working out at all. So I'm deleting it so that the developers can spend the time working in their out-of-tree location and get things cleaned up properly to get merged into the tree correctly at a later date. Because of these file removals, you will have merge issues on some of these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the atomisp driver).

2018-04-23staging: fsl-dpaa2/rtc: add rtc driverYangbo Lu7-2/+1251
This patch is to add driver for the DPAA2 1588 timer module (RTC) which interfaces to up to an unlimited number of 10/100/1000 or 10G ethernet MACs, providing current time, alarm, and fiper support. The 1588 IP control block includes these distinctive features. - External GPIO trigger for time-stamping - 2 Time-stamp alarms - 3 FIPER pulse generators - Phase adjusted output timer clock Currently this driver only supports basic functions like settime/gettime/adjtime/adjfreq.

2018-04-23staging: fsl-dpaa2/ethsw: Fix tag control information value overwriteRazvan Stefanescu4-19/+79
The tag control information (TCI) part of the VLAN header contains several fields, including PCP (priority code point) and PVID (port VLAN id). Current implementation uses function ethsw_port_set_tci() to set the PVID value and mistakenly overwrites the rest of the TCI fields with 0, including PCP which by default has a value of 7. Fix this by adding support to retrieve TCI set in hardware. Read existing value and only updated the PVID fields, leaving others unchanged.

2018-03-23staging: fsl-dpaa2/eth: Change max number of Tx queuesIoana Radulescu1-2/+2
We use DPAA2_ETH_MAX_TX_QUEUES to dimension the array holding information on Tx queues. At most, we can have one queue per cpu. Until now we used the NR_CPUS macro to set the upper limit on number of Tx queues. However, the platforms that the DPAA2 Ethernet driver supports have at most 16 cores, whereas NR_CPUS is Kconfigurable and can be much higher. Avoid allocating memory we'll never use, by setting DPAA2_ETH_MAX_TX_QUEUES to 16. Same for DPAA2_ETH_MAX_DPCONS.
