Updated libmlx4 packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The libmlx4 packages provide a device-specific user space driver for Mellanox ConnectX InfiniBand adapter cards for use with the libibverbs library.
Prior to this update, editing the /etc/ofed/mlx4.conf configuration file to change a port on a Mellanox ConnectX InfiniBand host channel adapter (HCA) to "eth" (Ethernet) could cause various errors to occur. This update corrects this error, and such a port can now be changed as expected.
All users of Mellanox ConnectX InfiniBand adapter cards are advised to upgrade to these updated packages, which fix this bug.
