We replaced the uses of struct tcp_hdr with the equivalent struct tcp_header. Remove the unused one. Signed-off-by: Philippe Mathieu-Daud=C3=A9 --- I prefer the TCP_FLAG_XXX name, but there is only one single use of TCP_FLAG_ACK vs many use of the other set, so I'm keeping the set. include/net/eth.h | 40 ++++++++-------------------------------- 1 file changed, 8 insertions(+), 32 deletions(-) diff --git a/include/net/eth.h b/include/net/eth.h index 7f45c678e7..0b2584328a 100644 --- a/include/net/eth.h +++ b/include/net/eth.h @@ -72,7 +72,14 @@ typedef struct tcp_header { #define TCP_HEADER_FLAGS(tcp) \ TCP_FLAGS_ONLY(be16_to_cpu((tcp)->th_offset_flags)) =20 -#define TCP_FLAG_ACK 0x10 +#define TH_FIN 0x01 +#define TH_SYN 0x02 +#define TH_RST 0x04 +#define TH_PUSH 0x08 +#define TH_ACK 0x10 +#define TH_URG 0x20 +#define TH_ECE 0x40 +#define TH_CWR 0x80 =20 #define TCP_HEADER_DATA_OFFSET(tcp) \ (((be16_to_cpu((tcp)->th_offset_flags) >> 12) & 0xf) << 2) @@ -153,37 +160,6 @@ struct udp_hdr { uint16_t uh_sum; /* udp checksum */ }; =20 -struct tcp_hdr { - u_short th_sport; /* source port */ - u_short th_dport; /* destination port */ - uint32_t th_seq; /* sequence number */ - uint32_t th_ack; /* acknowledgment number */ -#ifdef HOST_WORDS_BIGENDIAN - u_char th_off : 4, /* data offset */ - th_x2:4; /* (unused) */ -#else - u_char th_x2 : 4, /* (unused) */ - th_off:4; /* data offset */ -#endif - -#define TH_ELN 0x1 /* explicit loss notification */ -#define TH_ECN 0x2 /* explicit congestion notification */ -#define TH_FS 0x4 /* fast start */ - - u_char th_flags; -#define TH_FIN 0x01 -#define TH_SYN 0x02 -#define TH_RST 0x04 -#define TH_PUSH 0x08 -#define TH_ACK 0x10 -#define TH_URG 0x20 -#define TH_ECE 0x40 -#define TH_CWR 0x80 - u_short th_win; /* window */ - u_short th_sum; /* checksum */ - u_short th_urp; /* urgent pointer */ -}; - #define ip6_nxt ip6_ctlun.ip6_un1.ip6_un1_nxt #define ip6_ecn_acc ip6_ctlun.ip6_un3.ip6_un3_ecn =20 --=20 2.20.1
