net/ice/base: correct swtch programming IPV6 header bitmask
Checks
Commit Message
Correct an error in the IPV6 header bitmask used for programming switch
rules. Also, change other programming switch headers to use big endian
fields in order to make setting these easier.
Fixes: 04b8ec1ea807 ("net/ice/base: add protocol structures and defines")
