Help about an 3c509 on redhat 7.3

Hello

I use kernel 2.4.18-3 from redhat 7.3 with a 3com etherlink III isa 3C509
on an Isa port. When I load the module (1.18c 03/01/02) into the system
and do a service network start, I can see this in the log file: 

mter sysctl: net.ipv4.ip_forward = 0
mter sysctl: net.ipv4.conf.default.rp_filter = 1
mter sysctl: kernel.sysrq = 0
mter sysctl: kernel.core_uses_pid = 1
mter network: Setting network parameters:  succeeded
mter network: Bringing up loopback interface:  succeeded
mter kernel: eth0: Setting 3c5x9/3c5x9B half-duplex mode if_port: 0, sw_info: 
1310
mter kernel: eth0: Setting Rx mode to 1 addresses.
mter network: Bringing up interface eth0:  succeeded

I am confused with the message "Rx mode to 1 addresses". Could you 
tell me how to solve this problem and is it possible to change the
values of the parameters (net.ipv4.ip_forward , kernel.sysrq...)

Thanks for your help
