Subject: [RFC 1/7] ieee80211: share 802.11 unit conversion helpers
Date:   Tue, 31 Mar 2020 23:21:44 -0700
Message-Id: <20200401062150.3324-2-thomas@adapt-ip.com>

Precedence: bulk

MHZ_TO_KHZ, and KHZ_TO_MHZ are useful to drivers and
elsewhere so export these in the common ieee80211 header.
Move the power helpers also because we might as well.
