Not clear. The file seems to be comma AND multiple space delimited. AND, first four lines (and next four ... etc.) seem to contain identical values. It's easy to set a flag on a field changing, but to what avail? Where does $1 == "1" into play? I don't see a connection between your input sample and the desired output you post. Pls be more specific, post more detailed input / output samples.
And, btw, don't use $f in your awk script. That's a shell'ism; use f to reference the variable itself. In awk, $f would address the f'th field of the input line...

msgb(9S) Data Structures for Drivers msgb(9S)
NAME
msgb, mblk - STREAMS message block structure
SYNOPSIS
#include <sys/stream.h>
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI)
DESCRIPTION
A STREAMS message is made up of one or more message blocks, referenced by a pointer to a msgb structure. The b_next and b_prev pointers
are used to link messages together on a QUEUE. The b_cont pointer links message blocks together when a message consists of more than one
block.
Each msgb structure also includes a pointer to a datab(9S) structure, the data block (which contains pointers to the actual data of the
message), and the type of the message.
STRUCTURE MEMBERS
struct msgb *b_next; /* next message on queue */
struct msgb *b_prev; /* previous message on queue */
struct msgb *b_cont; /* next message block */
unsigned char *b_rptr; /* 1st unread data byte of buffer */
unsigned char *b_wptr; /* 1st unwritten data byte of buffer */
struct datab *b_datap; /* pointer to data block */
unsigned char b_band; /* message priority */
unsigned short b_flag; /* used by stream head */
Valid flags are as follows:
MSGMARK Last byte of message is marked.
MSGDELIM Message is delimited.
The msgb structure is defined as type mblk_t.
