I don't have a strong preference because I can't find a good name.
Consistency in naming this feature is the most important part.
Maybe it is just me who is reading it this way, but I associate a
structure whose name contains "hdr" with something that pertains to data
from an skb (such as "mgmt_ethhdr" which is exactly that), hence the
earlier comment. I opened the manual and the phrasing that the vendor
uses is that "[ the switch ] supports the read/write register (sic)
through the Atheros header". So it makes more sense now and it's in line
with that, at least to some degree. I understand if you prefer not to
change it, but "mgmt_data" sounds less confusing to me.
