[ewg] FW: [PATCH] compat-rdma-3.5: Changes to makefile

[Nikolova, Tatyana E]

After testing OFED-3.5-20120716-0723 with linux-3.5.0-rc6, RHEL 6.2, RHEL 6.3 and SLES 11-SP2, it appears that CONFIG_COMPAT_SKB_FRAG_NEEDED is always 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,
Tatyana

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.
