e1000e: drop unnecessary constant casts to u16

2025-09-03T17:07:27Z

Remove unnecessary casts of constant values to u16. C's integer promotion rules make them ints no matter what. Additionally replace E1000_MNG_VLAN_NONE with resulting value rather than casting -1 to u16.

e1000e: ignore uninitialized checksum word on tgp

2025-07-21T17:31:09Z

As described by Vitaly Lifshits: > Starting from Tiger Lake, LAN NVM is locked for writes by SW, so the > driver cannot perform checksum validation and correction. This means > that all NVM images must leave the factory with correct checksum and > checksum valid bit set. Unfortunately some systems have left the factory with an uninitialized value of 0xFFFF at register address 0x3F (checksum word location). So on Tiger Lake platform we ignore the computed checksum when such condition is encountered.

e1000e: Reduce boot time by tightening sleep ranges

2019-06-28T22:59:52Z

The e1000e driver is a great user of the usleep_range() API, and has nice ranges that in principle help power management. However the ranges that are used only during system startup are very long (and can add easily 100 msec to the boot time) while the power savings of such long ranges is irrelevant due to the one-off, boot only, nature of these functions. This patch shrinks some of the longest ranges to be shorter (while still using a power friendly 1 msec range); this saves 100msec+ of boot time on my BDW NUCs Signed-off-by: Arjan van de Ven Signed-off-by: Paul Menzel Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

net: intel: Cleanup the copyright/license headers

2018-04-27T18:00:04Z

After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.

e1000e: use BIT() macro for bit defines

2016-05-13T22:15:36Z

This prevents signed bitshift issues when the shift would overwrite the signed bit, and prevents making this mistake in the future when copying and modifying code. Use GENMASK or the unsigned postfix for cases which aren't suitable for BIT() macro. Signed-off-by: Jacob Keller Signed-off-by: Jeff Kirsher
