Tue Dec 21 09:59:46 CET 2010
Add Faraday's ftgmac100 (gigabit ethernet)
MAC controller's driver.
Signed-off-by: Macpaul Lin <macpaul at andestech.com>
---
Changes for v2:
- Coding Style cleanup
- Makefile Order sorted
- Volatile statement eliminated
- Error handling added
- Autonegotiation timeout value rechecked
- Link speed detection code is reduced
- Logic of autonegotiation and Link speed update reorganized
- Redundent registers offset table cleared
- The explaination of sub configuration of this
driver has moved into README
Changes for v3:
- Coding Style clean up about
- 2 continue blank line
- incorrect multi-line comment style
- useless else statement and return value statement
- make multi-line statement into single line which doesn't exceed 80 chars
- brance with multi-line statement (comments included before one line code)
