-// Procedure: phs_compress
-//
-// Description: This routine suppresses the static fields within the packet.Before
-// that it will verify the fields to be suppressed with the corresponding fields in the
-// phsf. For verification it checks the phsv field of PHS rule. If set and verification
-// succeeds it suppresses the field.If any one static field is found different none of
-// the static fields are suppressed then the packet is sent as uncompressed packet with
-// phsi=0.
-//
-// Arguments:
-// phs_rule - ptr to PHS rule.
-// in_buf - ptr to incoming packet buffer.
-// out_buf - ptr to output buffer where the suppressed header is copied.
-// header_size - ptr to field which holds the phss.
-//
-// Returns:
-// size-The number of bytes copied into the output buffer i.e dynamic fields
-// 0 -If PHS rule is NULL.If PHSV field is not set.If the verification fails.
