I just got an Intel PRO/1000 CT pci-e nic (82574L) and am running oi_151. This nic is handled by the e1000g(7D) driver. e1000g(7D) on an s11e box (oi_151 still doesn't have this and other manpages yet) lists this nic is capable of a maximum MTU of 9216 (i reckon the s11e driver is identical to the one used on oi_151).
from e1000g(7D):
For a Intel PRO/1000 adapter that is later than 82571
(including 82571) the maximum MTU accepted by the MAC is
9216. For others, the maximum MTU accepted by the MAC is
16298. Use ifconfig(1M) to configure jumbo frames. Using
ifconfig with the adapter instance and the mtu argument
(ifconfig e1000g0 mtu 9216) configures adapter e1000g0
for the maximum allowable jumbo frame size.
However output from both ipadm(1M) and dladm(1M) shows only a maximum MTU of
1500 to be possible.
I've tried setting an MTU of 9000 as follows:
using ipadm(1M):
solaris% pfexec ipadm set-ifprop -t -p mtu=9000 -m ipv4 e1000g0
ipadm: set-ifprop: mtu: Invalid argument provided
Anything lower than 1500 gets accepted by this command, anything over returns
said error.
using ifconfig(1M):
solarisexpress% pfexec ifconfig e1000g0 mtu 9000
ifconfig: setifmtu: SIOCSLIFMTU: e1000g0: Invalid argument
Is there something I'm missing i.e. is there something else I need to do to
enable jumboframes on this nic?
cheers
