Solaris 10 5/09 OS is the first release of Solaris to support the Sun Dual 10GbE SFP+ PCIe 2.0 Low Profile Adapter and other Intel 82599 10GbE controller-based adapters. The Solaris ixgbe driver, version 1.0.9 and later, supports both the Intel 82599 and Intel 82598 families of network controllers.
The ixgbe drive comes bundled with the Solaris OS. Depending on your version of the Solaris 10 OS, you might or might not need to download the updated driver.
Check the version of the installed driver to ensure that the adapter is properly loaded and is recognized by the Solaris OS.
# modinfo | grep ixgbe 173 7b762000 17998 100 1 ixgbe (Intel 10Gb Ethernet 1.0.9)
If the version number is not 1.0.9 or later, you must install the latest driver patch. See OS Patches and Updates.
Note - If the ixgbe driver is not listed, the driver might not be loaded. You can use the modload command to load the driver if needed. See the modload(1M) man page.
Apply the necessary patch to get the latest driver:
# patchadd /absolute_path/patchID
See the patchadd(1M) man page for more information.
