From e51dbdb66391a5b51cf9822e074778eb536b76fc Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Tue, 5 Dec 2023 17:01:06 -0800 Subject: [PATCH] ice: fix pre-shifted bit usage BugLink: https://bugs.launchpad.net/bugs/2059284 [ Upstream commit 7173be21ae29ef50ada42fd4464056a9d3f55bb3 ] While converting to FIELD_PREP() and FIELD_GET(), it was noticed that some of the RSS defines had *included* the shift in their definitions. This is completely outside of normal, such that a developer could easily make a mistake and shift at the usage site (like when using FIELD_PREP()). Rename the defines and set them to the "pre-shifted values" so they match the template the driver normally uses for masks and the member bits of the mask, which also allows the driver to use FIELD_PREP correctly with these values. Use GENMASK() for this changed MASK value. Do the same for the VLAN EMODE defines as well.
