IB/mlx4: fix wrong info returned when querying IBoE ports
To issue port query, use the QUERY_(Ethernet)_PORT command instead of
MAD_IFC command as the latter attempts to query the firmware IB SMA agent,
which is irrelevant for IBoE ports. This allows to support both 10Gb/s and
40Gb/s rates (e.g in sysfs), using QDR speed (10Gb/s) and width of 1X or 4X.

3. Known Issues
===============================================================================
The following is a list of general limitations and known issues of the various
components of the OFED 1.5.4.1 release.
1. When upgrading from an earlier OFED version, the installation script does
not stop the earlier OFED version prior to uninstalling it.
Workaround: Stop the old OFED stack (/etc/init.d/openibd stop) before
upgrading to OFED 1.5.3 or reboot the server after OFED installation.
2. Memory registration by the user is limited according to administrator
setting. See "Pinning (Locking) User Memory Pages" in OFED_tips.txt for
system configuration.
3. Fork support from kernel 2.6.12 and above is available provided
that applications do not use threads. fork() is supported as long as the
parent process does not run before the child exits or calls exec().
The former can be achieved by calling wait(childpid), and the latter can be
achieved by application specific means. The Posix system() call is
supported.
4. The qib driver is supported only on 64-bit platforms.
5. When installing OFED on OpenSuse or Ubuntu, use the --without-depcheck
option of the install.pl script.
6. IPoIB: brctl utilities do not work on IPoIB interfaces. The reason for that
is that these utilities support devices of type Ethernet only.
7. "openibd stop" can sometime fail with the error:
Unloading ib_cm [FAILED]
ERROR: Module ib_cm is in use by ib_ipoib
Workaround: run "openibd stop" again or remove ib_ipoib aliases from
/etc/modprobe.d/ib_ipoib.conf.
8. When working with ISCSI over IPoIB or mlx4_en, you must disable LRO (even
if IPoIB is set to connected mode). This is due to a bug in older kernels
which causes a kernel panic.
9. On SLES11, and in case uninstall is failing, check the error log and remove
the remaining RPMs manually using 'rpm -e <rpms list>'.
10. On SLES11, set allow_unsupported_modules parameter to 1 in file:
/etc/modprobe.d/unsupported-modules. Without this the modules will not
load.
11. Kernel 3.1 is not officially suported.
Note: See the release notes of each component for additional issues.
