Subject[PATCH AUTOSEL 4.14 31/61] qed: Avoid implicit enum conversion in qed_iwarp_parse_rx_pkt
Date
From: Nathan Chancellor <natechancellor@gmail.com>

[ Upstream commit 77f2d753819b7d50c16abfb778caf1fe075faed0 ]

Clang warns when one enumerated type is implicitly converted to another.

drivers/net/ethernet/qlogic/qed/qed_iwarp.c:1713:25: warning: implicit
conversion from enumeration type 'enum tcp_ip_version' to different
enumeration type 'enum qed_tcp_ip_version' [-Wenum-conversion]
cm_info->ip_version = TCP_IPV4;
~ ^~~~~~~~
drivers/net/ethernet/qlogic/qed/qed_iwarp.c:1733:25: warning: implicit
conversion from enumeration type 'enum tcp_ip_version' to different
enumeration type 'enum qed_tcp_ip_version' [-Wenum-conversion]
cm_info->ip_version = TCP_IPV6;
~ ^~~~~~~~
2 warnings generated.

Use the appropriate values from the expected type, qed_tcp_ip_version:

TCP_IPV4 = QED_TCP_IPV4 = 0
TCP_IPV6 = QED_TCP_IPV6 = 1
