Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net
Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series implements the new i40e driver for Intel's upcoming Intel(R) Ethernet Controller XL710 Family of devices. V7: many changes from a few comments: use linux errno types change I40E_SUCCESS to 0, standardize returns change s32 return values to int use void return values where possible prefer use of int over i40e_status V6: rename Kbuild to Makefile rename i40e_mem[set|cpy] to regular memset/memcpy V5: remove sysfs support from this set, will rearchitect changes from community comments V4: addresses remaining community comments, mostly trivial edits. major sparse based cleanup of possible endian issues removal of most of __func__ references sizeof(*var) instead of sizeof(struct ...) change 'NULL ==' tests to !NULL implement xps use kernel bitshift macros (upper_32_bits, etc) V3: many more individual comments addressed, thanks reviewers! Many other changes due to internal review and development. V2: each patch has individual comments, in general, feedback from the list was applied and addressed. Many changes due to internal review and coding as well. V1: initial send Let me start by saying thanks and we appreciate any time spent by those of you who review and comment on this new driver, and we will attempt to address and respond to all issues brought to our attention. I tried to break the patches up to ease review, but the series should apply and still be bisectable, as the last patch adds the driver to the kernel compile with CONFIG_I40E. This driver is for a brand new bit of silicon that has a different design than other Intel Ethernet silicon, and therefore needed a new driver. The hardware has quite a bit of capability and this driver is only meant to provide basic functionality at first. Future patches will continue to add functionality and bug fixes. This initial release is very early in the product cycle with the intent of getting initial support into the kernel before users have the hardware available to purchase. A software development manual is not ready yet but will be available when the hardware ships. The driver development model and interaction with community submitted patches *will not be any different* than what we are currently doing today. We plan to continue established processes. An associated i40evf driver has been posted for review. List of tools we ran in preparation: way more sparse clean make W=1, W=2 clean checkpatch (almost) clean total: 1 errors, 4 warnings, 30461 lines checked NOTE: Ignored message types: LONG_LINE - issues have been addressed and the remainders are noise. codespell clean smatch (almost) clean with a couple minor warnings coccicheck clean namespacecheck clean allmodconfig clean ppc64 build clean (untested) This driver is a team effort, thank you to Joseph Gasparakis, Shannon Nelson, Anjali Singhai-Jain, Mitch Williams, Neerav Parikh, Vasu Dev, Kavindya Deegala, Yi Zou, and PJ Waskiewicz. TODO (known issues) BQL implementation finish rtnl_stat64 locking (we have a patch but debugging it) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
