Proto:static inline __be16 udp_flow_src_port(struct net *net, struct sk_buff *skb, int min, int max, bool use_eth)

Type:__be16

Parameter:

TypeParameterName
struct net *net
struct sk_buff *skb
intmin
intmax
booluse_eth
215  If min >= max Then
217  inet_get_local_port_range(net, & min, & max)
220  hash = skb_get_hash(skb)
221  If Value for the false possibility is greater at compile time(!hash) Then
222  If use_eth Then
226  hash = jhash - hash an arbitrary key*@k: sequence of bytes as key*@length: the length of the key*@initval: the previous hash, or an arbitray value* The generic version, hashes an arbitrary sequence of bytes.
228  Else
232  hash = udp_flow_hashrnd()
241  hash ^= hash << 16
243  Return htons((((u64)hash * (max - min)) >> 32) + min)
