:Okay, I patched if_rl.c in -current to fixe the problem demonstrated by
:Matt's linktest program. The bug was actually on the receive side of the
:rl driver, not the transmit side. A packet can wrap from the end of the
:RX buffer back to the beginning, and in some cases these packets would
:get lost due to botched use of m_pullup(). I can run the linktest
:program now without losing any frames.
:
:There's another way around this which is to allocate a whole mbuf
:cluster when you know the packet is wrapped and bcopy the data manually
:instead of using m_devget(), but I'm not sure I want to waste a whole
:cluster just for that case.
