Hi Vlad,
I am getting a build failure while building cxgb3 and cxgb4 drivers together.
The errors are coming because of wrong inclusion of header files. To be precise
it includes cxgb3 header files while trying to compile iw_cxgb4 driver. Due to
this I am getting following build failure.

=====
cxgb4_l2t_send function is declared in l2t.h file. This l2t.h file is present
in both cxgb3 as well as cxgb4 directories. Since in above command cxgb3 path
is included first, l2t.h file also gets included from there. If I include cxgb4
path first then this error is not coming.
Please suggest how should I go to fix this?
Thanks,
Vipul
