URL: https://svnweb.freebsd.org/changeset/base/294198
Log:
urtwn: add ROM structure for RTL8188EU
- Add the structure with already known fields offsets
(some of them were taken from this driver,
some (channel_plan, rf_* fields) - from TP-LINK official driver)
- Fix a typo / dehardcode a constant in RTL8192C ROM structure.
Tested with RTL8188EU, STA mode
