Gigabit Ethernet Driver .....

Post by Franci » Wed, 03 Oct 2001 19:42:23



Hi team,
    I have a machine which has "gigabit ethernet" card installed on the
system, but could not detect the interface upon booting up (I did a
"boot -r" at OBP prompt).

    I checked on another system which also has "gigabit ethernet" card
installed on the system and was able to detect the interface.

    The difference is I found out that one of the system does not have
the "Gigabit" driver installed.

    Do I need to install the driver in order for the system to detect
the interface and then configure it.

    I am just wondering if I could copy the driver fr one system to
another. If so, where could I get the driver s/w. If not, where can I
get the driver ??

    Please help.

Regards,
Francis.

If you have similar GigE cards, you should install the same package on
both computers, containing the same kernel driver. To find out package
name check for driver's full path in the 'contents' database:

  % grep /kernel/drv/ge /var/sadm/install/contents
  /kernel/drv/ge f none 0755 root sys 136592 26280 968268237 SUNWged
  % pkginfo SUNWged
  system      SUNWged        Sun Gigabit Ethernet Adapter Driver

   Yes.  No driver, no interface.

   See if you have a CD-ROM around somewhere with the driver on it.
   Is this the Sun GE adapter, or the Sun/Alteon VGE adapter?  
   The latter is good only up to Solaris 2.6.

   Honestly can't remember if this driver is available from the
   Sun website, and it is always so pathetically slow....  

 
 
 

1. Is jumbo ethernet MTU possible with Hamachi Gigabit ethernet driver?

I'm trying to get some Gigabit ethernet cards that use the Packet
Engines Hamachi GNIC-II chip to use a large mtu to attempt to get a
throughput of close to the 1Gb rating of the card.  This is on a Compact
PCI Alpha system.  I'm trying to use an MTU in the 8000 to 9000 range
and so far have not been able to get these MTUs to work.

I have changed the PKT_BUF_SZ and MAX_FRAME_SIZE constants in hamachi.c
and ETH_DATA_LEN and ETH_FRAME_LEN in if_ether.h.  I can use ifconfig to
change the MTU above 1500 on one side of a connection but as soon as I
raise the MTU on both sides to greater than 1500 the link dies.  I can
change the MTU with ifconfig back to 1500 and the link will resume
operation.  We are currently somewhat married to the 2.2.14 kernel.

I read that some ethernet drivers will support jumbo MTUs.  There
appears to be something in the hamachi driver or the kernel that I've
missed.  Perhaps this only works with a later version kernel or the
hamachi driver needs more changes?  Any help would be appreciated.
