On EF10, hardware filter IDs are 13 bits, but in some places we store 32-bit "full filter IDs" in which higher order bits encode the filter match-priority. This could cause a filter to have a full filter ID of 0xffff, which is also the value EFX_EF10_FILTER_ID_INVALID which we use in 16-bit "short" filter IDs (without match-priority bits). This would occur if the hardware filter ID was 0x1fff and the match-priority was 7. Unfortunately, some code that checks for EFX_EF10_FILTER_ID_INVALID can be called on full filter IDs, and will WARN_ON if this ever happens. So, since we have plenty of spare bits in the full filter ID, this patch shifts the priority bits left one bit when constructing the full filter IDs, ensuring that the 0x2000 bit of a full filter ID will always be 0 and thus no full filter ID can ever equal EFX_EF10_FILTER_ID_INVALID. This patch also replaces open-coded full<->short filter ID conversions with calls to functions, thus keeping the definition of the full filter ID format in one place.
