[ Upstream commit fbd825fcd7dd4c11d4c48c3d0adc248a4a0ce90b ]
Struct hsr_sup_tlv describes HW layout and therefore it needs a __packed attribute to ensure the compiler does not add any padding. Due to the size and __packed attribute of the structs that use hsr_sup_tlv it has no functional impact.
Add __packed to struct hsr_sup_tlv.
