New Revision: 302186
URL: https://svnweb.freebsd.org/changeset/base/302186
Log:
urtwn: use m_get2() in Rx path.
Replace m_getcl() with m_get2(); this fixes 'frame too long'
messages for frames, which are longer than MCLBYTES
(can be easily triggered when A-MSDU is used).
Tested with RTL8188CUS (AP) and RTL8188EU (STA).
