From: Paul Rolland <[email protected]>
Hello,
This patch is based on Linux 2.4.32, and I've verified the same problem
exists on 2.6.15.4.
Working on a machine with a 2.4.32 kernel, I was surprised to see the driver
complaining when setting the speed to 100FD using mii-tool, but accepting
the setting with ethtool.
Digging into the code, I found that there is some confusion with :
- DUPLEX_FULL and FULL_DUPLEX,
- DUPLEX_HALF and HALF_DUPLEX
in the code :
...
spddplx += (mii_reg & 0x100)
? FULL_DUPLEX :
HALF_DUPLEX;
retval = e1000_set_spd_dplx(adapter,
spddplx);
Please try this patch:
e1000: fix mii-tool access to setting speed and duplex
Paul Rolland reported that e1000 was having a hard time using mii-tool to
set speed and duplex. This patch fixes the issue on both newer hardware as
well as fixing the code issue that originally caused the problem.
