Subject: Ethtool doesn't work on Debian unstable?
Date: Thu, 10 Mar 2005 13:54:35 -0800 [thread overview]
Message-ID: <20050310135435.23af10b8@es175> (raw)
This is wierd. I know I am doing something Real Stupid, but i can't figure it out.
Two systems. 2.6.11 kernel on both systems.
One runs RedHat 9.0, and ethtool Just Works:
ethtool -g eth0
Ring parameters for eth0:
Pre-set maximums:
RX: 256
RX Mini: 0
RX Jumbo: 0
TX: 256
Current hardware settings:
RX: 64
RX Mini: 0
RX Jumbo: 0
TX: 64
--------------------
The other is Debian unstable, and nothing works:
ethtool -g eth0
Ring parameters for eth0:
Cannot get device ring settings: Operation not supported
------------------------
If i strace, i see the ioctl failing on the Debian side:
7657 munmap(0xb7fd6000, 75321) = 0
7657 socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 3
7657 fstat64(1, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 5), ...}) = 0
7657 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7fe8000
7657 write(1, "Ring parameters for eth1:\n", 26) = 26
7657 ioctl(3, SIOCETHTOOL, 0xbffffd30) = -1 EOPNOTSUPP (Operation not supported)
7657 dup(2) = 4
------------------------
Can anyone help me here? I'd like to use Debian for this testing, but so far, no love.
