[2/4] net/mlx5/hws: fix GENEVE option class partial mask
Checks
Commit Message
When GENEVE option parser is configured, the class field has 3 optional
modes:
1. ignored - ignore this field.
2. fixed - this field is part of option identifier along with type
field. In this mode, the exact value is provided in "spec"
field during pattern template creation and mask must be 0xffff.
3. matchable - class field isn't part of the identifier and only mask is
provided in pattern template creation. The mask can be
any value like all other fields.
In current implementation, when class mask isn't 0, pattern template
creation is failed for mask != 0xffff regardless to class mode.
This patch fixes this validation to be only when class mode is fixed.
