New Revision: 322949
URL: https://svnweb.freebsd.org/changeset/base/322949
Log:
rtwn(4): change type for Tx power values (RTL8192C / RTL8188EU).
Tx power values can easily fit into uint8_t + only 8 bits are written
to registers; values may overflow only in case if ROM contains
malformed data (but limit is checked anyway).
Tested with RTL8188CUS, dev.rtwn.1.debug=0x2000 (no changes).
