* Fall back to ether_ioctl() by default.Brooks Davis2018-03-301-7/+1
| | | | | | | | | | | | | | | | | | | | The common pratice in ethernet device drivers is to fall back to ether_ioctl() to implement generic ioctls not implemented by the driver and to fail if no handler exists. Convert these drivers to follow that practice rather than calling ether_ioctl() for specific cases. vxge(4) aready had the default case, but it was only called on failure to match.

* Use an accessor function to access ifr_data.Brooks Davis2018-03-301-13/+15
| | | | | | | | | | | | | | | | This fixes 32-bit compat (no ioctl command defintions are required as struct ifreq is the same size). This is believed to be sufficent to fully support ifconfig on 32-bit systems.

* Don't access userspace directly from the kernel in nxge(4).Brooks Davis2018-03-271-5/+16
| | | | | | | | | | | | | | | Update to what the previous code seemed to be doing via the correct interfaces. Further issues exist in xge_ioctl_registers(), but this is debugging code in a driver that has few users and they don't appear to be crashes or leaks.

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2739-0/+78
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

Previously, Ethernet frames received in contiguous buffers were offloaded. Now, frames received in multiple non-contiguous buffers can be offloaded, as well. The driver now supports LRO for jumbo frames. 02 - Locks Optimization: The driver code was re-organized to limit the use of locks. Moreover, lock contention was reduced by replacing wait locks with try locks. 03 - Code Optimization: The driver code was re-factored to eliminate some memcpy operations. Fast path loops were optimized. 04 - Tag Creations: Physical Buffer Tags are now optimized based upon frame size. For better performance, Physical Memory Maps are now re-used. 05 - Configuration: Features such as TSO, LRO, and Interrupt Mode can be configured either at load or at run time. Rx buffer mode (mode 1 or mode 2) can be configured at load time through kenv. 06 - Driver Statistics: Run time statistics are enhanced to provide better visibility into the driver performance. 07 - Bug Fixes: The driver contains fixes for the problems discovered and reported since last submission. 08 - MSI support: Added Message Signaled Interrupt feature which currently uses 1 message. 09 Removed feature: Rx 3 buffer mode feature has been removed. Driver now supports 1, 2 and 5 buffer modes of which 2 and 5 buffer modes can be used for header separation. 10 Compiler warning: Fixed compiler warning when compiled for 32 bit system. 11 Copyright notice: Source files are updated with the proper copyright notice.
