* Refresh on the shared code for the E1000 drivers.jfv2013-02-211-3/+5
| | | | | | | | | | | | | | | | | | | | - bear with me, there are lots of white space changes, I would not do them, but I am a mere consumer of this stuff and if these drivers are to stay in shape they need to be taken. em driver changes: support for the new i217/i218 interfaces igb driver changes: - TX mq start has a quick turnaround to the stack - Link/media handling improvement - When link status changes happen the current flow control state will now be displayed. - A few white space/style changes. lem driver changes: - the shared code uncovered a bogus write to the RLPML register (which does not exist in this hardware) in the vlan code,this is removed.
* Sync with Intel internal source:jfv2012-07-051-1/+3

* Part 1 of two parts, this is the shared code changes injfv2011-12-101-78/+76
| | | | | | | | | | | | | support of new deltas for both em and igb drivers. Note that I am not able to track all the bugs fixed in this code, I am a consumer of it as a component of my core drivers. It is important to keep the FreeBSD drivers up to date with it however. One important note is there is a key fix for 82574 in this update. Also, there are lots of white space changes, I am not happy about them but have no control over it :)
* Fix the shared code to be consistent with Intel-internal,jfv2011-02-121-2/+0

* Restore 2 prototypes that seem to have been mistakenly removed in r218582.dougb2011-02-111-0/+2
| | | | | | | | I've manually twiddled the whitespace for e1000_commit_fc_settings_generic to match the others in the file. Submitted by: dim Tested by: me

* Add support for the new I350 family of 1G interfaces.jfv2011-02-111-1/+0
| | | | | | | | | | | | | | | | | | | | | | | - this also includes virtualization support on these devices Correct some vlan issues we were seeing in test, jumbo frames on vlans did not work correctly, this was all due to confused logic around HW filters, the new code should now work for all uses. Important fix: when mbuf resources are depeleted, it was possible to completely empty the RX ring, and then the RX engine would stall forever. This is fixed by a flag being set whenever the refresh code fails due to an mbuf shortage, also the local timer now makes sure that all queues get an interrupt when it runs, the interrupt code will then always call rxeof, and in that routine the first thing done is now to check the refresh flag and call refresh_mbufs. This has been verified to fix this type 'hang'. Similar code will follow in the other drivers. Finally, sync up shared code for the I350 support. Thanks to everyone that has been reporting issues, and helping in the debug/test process!!
* Update code from Intel:jfv2010-09-281-0/+3
| | | | | | | | | | | | | | - Sync shared code with Intel internal - New client chipset support added - em driver - fixes to 82574, limit queues to 1 but use MSIX - em driver - large changes in TX checksum offload and tso code, thanks to yongari. - some small changes for watchdog issues. - igb driver - local timer watchdog code was missing locking this and a couple other watchdog related fixes. - bug in rx discard found by Andrew Boyer, check for null pointer MFC: a week
* OK, I was a bit sleep this morning and checked injfv2010-06-301-0/+1
| | | | | | | | the core changes but left out the shared code, lol. Well, and a couple fixes to the core... hopefully this will all be complete now. Happy happy joy joy :)
* Update the 1G drivers, shared code sync with Intel,jfv2010-01-261-2/+2
| | | | | | | | | | igb now has a queue notion that has a single interrupt with an RX/TX pair, this will reduce the total interrupts seen on a system. Both em and igb have a new watchdog method. igb has fixes from Pyun Yong-Hyeon that have improved stability, thank you :) I wish to MFC this for 7.3 asap, please test if able.
* This delta syncs the em and igb drivers with Intel,jfv2009-04-101-3/+3
| | | | | | | adds header split and SCTP support into the igb driver. Various small improvements and fixes. MFC after: 2 weeks
* This delta is primarily a fix for es2lan devices thatjfv2008-11-261-1/+1
| | | | | | | | | | | | | will sometimes fail to initialize problem due to a lock contention with management hardware. However, in order to deliver that fix it was necessary to take a shared code update as a whole, and this required scattered changes in the core code to be compatible. The em driver now has VLAN HW support added as the igb driver had previously. MFC after: ASAP - in time for 7.1 RELEASE
* Merge of the source for igb and em into dev/e1000, thisjfv2008-07-301-0/+162
proved to be necessary to make the static drivers work in EITHER/OR or BOTH configurations. Modules will still build in sys/modules/igb or em as before. This also updates the igb driver for support for the 82576 adapter, adds shared code fixes, and etc.... MFC after: ASAP
