[ 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.
