[ofa-general] ibv_post_send implementation without doorbell

[अनुज]

hi

I have found fast path for implementation of ibv_post_send(), which
uses mthca_tavor_post_send() or mthca_arbel_post_send() defined in
libmthca/src/qp.c.

And in libibverbs ibv_cmd_post_send() is also defined which can be
used for slow path. For other user verbs corresponding ibv_cmd_* api's
are being used.

But it is seemed to no slow path support is provided by libmthca.

Please elaborate this point and explain how slow path can be used for
ibv_post_send().
