It seems that firmware has Tx TCP/UDP checksum offloading bug. - * The firmware hangs when it's told to compute TCP/UDP checksum. - * I'm not sure whether the firmware requires special alignment to - * do checksum offloading but datasheet says nothing about that. - * 2. Datasheet says nothing for maximum number of fragmented - * descriptors supported. Experimentation shows up to 16 fragment - * descriptors are supported in the firmware. For TSO case, upper - * stack can send 64KB sized IP datagram plus link header size( - * ethernet header + VLAN tag) frame but controller can handle up - * to 64KB frame given that PAGE_SIZE is 4KB(i.e. 16 * PAGE_SIZE). - * Because frames that need TSO operation of hardware can be - * larger than 64KB I disabled TSO capability. TSO operation for - * less than or equal to 16 fragment descriptors works without - * problems, though. - * 3. VLAN hardware tag stripping is always enabled in the firmware - * even if it's explicitly told to not strip the tag. It's - * possible to add the tag back in Rx handler if VLAN hardware - * tag is not active but I didn't try that as it would be - * layering violation. - * 4. TXP_CMD_RECV_BUFFER_CONTROL does not work as expected in - * datasheet such that driver should handle the alignment - * restriction by copying received frame to align the frame on - * 32bit boundary on strict-alignment architectures. This adds a - * lot of CPU burden and it effectively reduce Rx performance on - * strict-alignment architectures(e.g. sparc64, arm and mips). - * - * Unfortunately it seems that 3Com have no longer interests in - * releasing fixed firmware so we may have to live with these bugs. - */ - -#define TXP_CSUM_FEATURES (CSUM_IP) - -/* - * Various supported device vendors/types and their names. - */ -static struct txp_type txp_devs[] = { - { TXP_VENDORID_3COM, TXP_DEVICEID_3CR990_TX_95, - "3Com 3cR990-TX-95 Etherlink with 3XP Processor" }, - { TXP_VENDORID_3COM, TXP_DEVICEID_3CR990_TX_97, - "3Com 3cR990-TX-97 Etherlink with 3XP Processor" }, - { TXP_VENDORID_3COM, TXP_DEVICEID_3CR990B_TXM, - "3Com 3cR990B-TXM Etherlink with 3XP Processor" }, - { TXP_VENDORID_3COM, TXP_DEVICEID_3CR990_SRV_95, - "3Com 3cR990-SRV-95 Etherlink Server with 3XP Processor" }, - { TXP_VENDORID_3COM, TXP_DEVICEID_3CR990_SRV_97, - "3Com 3cR990-SRV-97 Etherlink Server with 3XP Processor" }, - { TXP_VENDORID_3COM, TXP_DEVICEID_3CR990B_SRV, - "3Com 3cR990B-SRV Etherlink Server with 3XP Processor" }, - { 0, 0, NULL } -};
