Setting Properties For Nxge Devices Might Fail (Cr 6561389); Server Might Panic In Nxge_Start When Dupb Fails (Cr 6567838); To Disable Jumbo Frames - Fujitsu SPARC Enterprise T5120 Product Notes

Setting Properties for nxge Devices Might Fail
(CR 6561389)
This issue is resolved for servers running the Solaris 10 5/08 OS and later. If you are
running Solaris 10 8/07, you can fix this issue with patch ID 127127-11 or later.
Setting a property for an nxge device node might not work correctly. The following
is an example:
name="SUNW,niusl" parent="/niu@80" unit-address="0" accept_jumbo=1;
name="SUNW,niusl" parent="/niu@80" unit-address="1" accept_jumbo=1;
Entries from /etc/path_to_inst:
/niu@80" 0 niumx
/niu@80/network@0" 0 nxge
/niu@80/network@1 1 nxge
Entries from /etc/driver_aliases:
niumx "SUNW,niumx
nxge "SUNW,niusl
Workaround: Use the global declaration without the device path in the nxge.conf
file. For example, add the following line to the nxge.conf file.
accept_jumbo = 1;

If Jumbo Frames are enabled, it is possible for the system to panic as a result of a
NULL pointer reference. This scenario is only possible when frame sizes are larger
than 4076. Jumbo Frames with MTU=9194 do not experience this problem.
Workaround: Disable Jumbo Frames or use a smaller MTU size as described in the
following procedures.

Jumbo Frames.
