Subject: [PATCH 4.14 095/115] bnxt_en: Fix population of flow_type in bnxt_hwrm_cfa_flow_alloc()

4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Sunil Challa <sunilkumar.challa@...adcom.com>


[ Upstream commit 7deea450eb912f269d999de62c8ab922d1461748 ]

flow_type in HWRM_FLOW_ALLOC is not being populated correctly due to
incorrect passing of pointer and size of l3_mask argument of is_wildcard().
Fixed this.

Fixes: db1d36a27324 ("bnxt_en: add TC flower offload flow_alloc/free FW cmds")
