After testing OFED-3.5-20120716-0723 with linux-3.5.0-rc6, RHEL 6.2, RHEL 6.3

undefined when building compat-rdma-3.5, which results in build errors for RHEL
6.2 and SLES 11-SP2.
The change to the makefile is a suggested fix. It is up to you how/where to
define CONFIG_COMPAT_SKB_FRAG_NEEDED
Sorry, if I sent the patch more than once, I don't see it in openfabrics
mailing list
Thanks,

Subject: [PATCH] compat-rdma-3.5: Changes to makefile
CONFIG_COMPAT_SKB_FRAG_NEEDED is defined in the makefile.
It is necessary for kernels < linux-3.2 except for RHEL 6.3
(linux-2.6.32-279.el6) where CONFIG_COMPAT_SKB_FRAG_NEEDED should not be defined.
