IB/mthca: Schedule MSI support for removal
The mthca driver supports both MSI and MSI-X. However, MSI-X works with all hardware that the driver handles, and provides a superset of what MSI does, so there's no point in having code for both. Schedule MSI support for removal in 2008 to give anyone who actually needs MSI and who can't use MSI time to speak up. Signed-off-by: Roland Dreier <rolandd@cisco.com>
