Yes. Linux could do crash dump through network by the way of netdump. by now Redhad obsoleted netdump by kdump. I tried kdump on iSCSI booted machine, it fails.
From the survey I had done. netdump is done through the way of "netpoll" infrastructure which is used to support low-level kernel functions which may need to be able to send and receive packets over the network without involving the entire networking subsystem and without enabling interrupts. So from here, there are strong reasons that Solaris network infrastructure need support this feature in order to support network dumping in the near future.
