* e1000e: cosmetic cleanup of commentsBruce Allan2012-12-01
| | | | | | | | | | Update comments to conform to the preferred style for networking code as described in ./Documentation/CodingStyle and checked for in the recently added checkpatch NETWORKING_BLOCK_COMMENT_STYLE test.

* e1000e: implement MDI/MDI-X controlJesse Brandeburg2012-08-21
| | | | | | | | | | | | | | | | | | | | | Some users report issues with link failing when connected to certain switches. This gives the user the ability to control the MDI state from the driver, allowing users to work around some improperly behaving switches. Forcing in this driver is for now only allowed when auto-neg is enabled.

* e1000e: Program the correct register for ITR when using MSI-X.Matthew Vick2012-07-14
| | | | | | | | | | | | | | When configuring interrupt throttling on 82574 in MSI-X mode, we need to be programming the EITR registers instead of the ITR register. -rc2: Renamed e1000_write_itr() to e1000e_write_itr(), fixed whitespace issues, and removed unnecessary !! operation. -rc3: Reduced the scope of the loop variable in e1000e_write_itr().

* e1000e: test for valid check_reset_block function pointerBruce Allan2012-06-05
| | | | | | | | | | | | commit 44abd5c12767a8c567dc4e45fd9aec3b13ca85e0 introduced NULL pointer dereferences when attempting to access the check_reset_block function pointer on 8257x and 80003es2lan non-copper devices. This fix should be applied back through 3.4.

* e1000e: cleanup - check return values consistentlyBruce Allan2012-02-07
| | | | | | | | | | | The majority of the e1000e code checks most function return values using a test like 'if (ret_val)' or 'if (!ret_val)' but there are a few instances of 'if (ret_val == 0)'. This patch converts the latter to the former for consistency.

* e1000e: add Receive Packet Steering (RPS) supportBruce Allan2012-01-26
| | | | | | | | | | | | | | | | | | | | Enable RPS by default. Disallow jumbo frames when both receive checksum and receive hashing are enabled because the hardware cannot do both IP payload checksum (enabled when receive checksum is enabled when using packet split which is used for jumbo frames) and provide RSS hash at the same time. v2: added ethtool command to query flow hashing behavior per Ben Hutchings and changed the type of rsskey to cleanup the setting of the register array and avoid unnecessary casts (as pointed out by Joe Perches). The long error messages are not changed since there is nothing in the kernel ./Documentation that suggests the preferred method for dealing with long messages other than to never break strings; leaving them as-is for now.

| | | | | | | | | | | | | | | | | | | | | | | | Some features currently not supported by the driver (e.g. RSS) require the use of extended descriptors, but the driver is setup to only use legacy descriptors in all modes except for when jumbo frames are enabled on some parts.
