Bill Paul	7437599f41	Fix some memory bugs with regard to jumbo buffers. I made a mistake when ... converting from the old external mbuf buffer code to the new (with the MEXTADD() macro). Also free free list memory correctly in foo_free_jumbo_mem() routines: grab the head of the list, then remove it, _then_ free() it. This fixes the memory corruption problem I've been chasing in the level 1 driver.	2001-06-18 22:04:40 +00:00
Bill Paul	c921560563	Turn TCP and UDP hardware RX checksumming back on. jlemon pointed out where ... I'd gone wrong before: we have to set csum_data to 0xffff, not 0.	2001-06-15 19:02:55 +00:00
Bill Paul	1c352ef74a	Use LGE_INC() macro to increment tx producer index in lge_encap(). ... Disable the extra TCP/UCP checksum checking in lge_rxeof() since it doesn't appear to actually work as advertised.	2001-06-06 19:16:02 +00:00
Bill Paul	6048cd628a	In lge_detach(), don't contigfree() the jumbogram buffer memory; ... lge_free_jumbo_mem() does it for us.	2001-06-05 23:16:52 +00:00
Bill Paul	c678bc4f13	Add device driver support for the Level 1 LXT1001 NetCellerator ... gigabit ethernet controller chip. This device is used on some fiber optic gigE cards from SMC, D-Link and Addtron. Jumbograms and TCP/IP checksum offload on receive are supported. Hardware VLAN filtering is not, because it doesn't play well with our existing VLAN code. Also add manual page. There is a 4.x version of this driver available at http://www.freebsd.org/~wpaul/Level1/4.x if anyone feels adventurous and wants to test it. I still need to do performance testing and tuning with this device. (For my next trick, I will make the 3Com 3cR990 sit up and beg.)	2001-05-31 21:44:26 +00:00
