- * known problems:

- * It may help to '#define RCV_PARANOIA_CHECK' or try to #undef
- * the XMT and RCV_VIA_SKB option .. this reduces driver performance.
- * Or just play with your BIOS options to optimize ISA-DMA access.
- * Maybe you also wanna play with the LOW_PERFORAMCE and MID_PERFORMANCE
- * defines -> please report me your experience then
- * - Harald reported for ASUS SP3G mainboards, that you should use
- * the 'optimal settings' from the user's manual on page 3-12!
- *
- * credits:
- * thanx to Jason Sullivan for sending me a ni6510 card!
- * lot of debug runs with ASUS SP3G Boards (Intel Saturn) by Harald Koenig
- *
- * simple performance test: (486DX-33/Ni6510-EB receives from 486DX4-100/Ni6510-EB)
- * average: FTP -> 8384421 bytes received in 8.5 seconds
- * (no RCV_VIA_SKB,no XMT_VIA_SKB,PARANOIA_CHECK,4 XMIT BUFS, 8 RCV_BUFFS)
- * peak: FTP -> 8384421 bytes received in 7.5 seconds
- * (RCV_VIA_SKB,XMT_VIA_SKB,no PARANOIA_CHECK,1(!) XMIT BUF, 16 RCV BUFFS)

-/*
- * 99.Jun.8: added support for /proc/net/dev byte count for xosview (HK)
- * 96.Sept.29: virt_to_bus stuff added for new memory modell
- * 96.April.29: Added Harald Koenig's Patches (MH)
- * 96.April.13: enhanced error handling .. more tests (MH)
- * 96.April.5/6: a lot of performance tests. Got it stable now (hopefully) (MH)
- * 96.April.1: (no joke ;) .. added EtherBlaster and Module support (MH)
- * 96.Feb.19: fixed a few bugs .. cleanups .. tested for 1.3.66 (MH)
- * hopefully no more 16MB limit
- *
- * 95.Nov.18: multicast tweaked (AC).
- *
- * 94.Aug.22: changes in xmit_intr (ack more than one xmitted-packet), ni65_send_packet (p->lock) (MH)
- *
- * 94.July.16: fixed bugs in recv_skb and skb-alloc stuff (MH)
