Add devices to the configuration file, +rebuild the kernel, and reboot. +.Pp +All other diagnostics indicate either a hardware problem or a bug in the +driver. +.Sh CAVEATS +Some early-revision 3c590 cards are defective and suffer from many receive +overruns, which cause lost packets. The author has attempted to implement +a test for it based on the information supplied by 3Com, but the test resulted +mostly in spurious warnings. +.Pp +The performance of this driver is somewhat limited by the fact that it uses +only polled-mode I/O and does not make use of the bus-mastering capability +of the cards. +.Sh BUGS +The +.Nm vx +driver is known not to reset the adapter correctly following a warm boot +on some systems. +.Pp +The +.Nm vx +driver has not been exhaustively tested with all the models of cards that it +claims to support. +.Sh HISTORY +The +.Nm vx +device driver first appeared in FreeBSD 2.1.0. It was derived from the +.Nm ep +driver, from which it inheirits most of its limitations. +.Sh AUTHOR +The +.Nm vx +device driver and this manual page were written by Fred Gray (fgray@rice.edu), +based on the work of Herb Peyerl and with the assistance of numerous others. |
