Subject: [PATCH 3.2 65/67] iw_cxgb3: Fix incorrectly returning error on
 success

3.2.78-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Hariprasad S <hariprasad@...lsio.com>

commit 67f1aee6f45059fd6b0f5b0ecb2c97ad0451f6b3 upstream.

The cxgb3_*_send() functions return NET_XMIT_ values, which are
positive integers values. So don't treat positive return values
as an error.
