Pyun YongHyeon 81eee0ebf8 Implement initial jumbo frame support for RTL8168/8111 C/D/E PCIe ... GbE controllers. It seems these controllers no longer support multi-fragmented RX buffers such that driver have to allocate physically contiguous buffers. o Retire RL_FLAG_NOJUMBO flag and introduce RL_FLAG_JUMBOV2 to mark controllers that use new jumbo frame scheme. o Configure PCIe max read request size to 4096 for standard frames and reduce it to 512 for jumbo frames. o TSO/checksum offloading is not supported for jumbo frames on these controllers. Reflect it to ioctl handler and driver initialization. o Remove unused rl_stats_no_timeout in softc. o Embed a pointer to structure rl_hwrev into softc to keep track of controller MTU limitation and remove rl_hwrev in softc since that information is available through a pointer to structure rl_hwrev. Special thanks to Realtek for donating sample hardwares which made this possible. H/W donated by: Realtek Semiconductor Corp.		2011-01-17 03:24:33 +00:00
