The ip1000 driver is for IC Plus 1000A/Family (ST1023) Ethernet card.
|
||||
|
||||
This driver is referred to Minix(3.4.0) vt6105 driver,
|
||||
This driver is referred to Minix(3.4.0) rtl8169 driver,
|
||||
Linux(4.2.1) ipg driver and IP1000A LF-DS-R08 datasheet.
|
||||
|
||||
The supported PCI number is 13F0:1023:13F0:1023.
|
||||
Maybe the Ethernet cards of other PCI numbers for IC Plus can be supported.

Modification: Restructure the code and correct function order in initialization
|
||||
Authored by Jia-Ju Bai <baijiaju1990@163.com>
|
||||
|
||||
Something can be improved:
|
||||
1. Ethernet address can not be modified at present.
|
||||
2. Dump interfaces are not provided.
|
||||
3. The device needs serveral seconds to work normally after initialization.
