Hi

tested with:
#include <stdio.h>
int main() {
    char padapter = 1;
    int pfree_recv_queue = 256;
    int free_recv_queue = 256;

    if (padapter) {
    	if (pfree_recv_queue == free_recv_queue)
            printf("Executed before patch: 
precvpriv->free_recvframe_cnt++;\n");
    }

    if (padapter && pfree_recv_queue == free_recv_queue)
		printf("Executed after patch: precvpriv->free_recvframe_cnt++;\n");

   return 0;
}

Seems to work. But the rules which operation is done first && or == are 
not too easy. I would prefer to have:

if (padapter && (pfree_recv_queue == free_recv_queue))

So it is very easy to read what is evaluated first.

But this is just my opinion and does not have to be right.

Thanks for your patch.

Bye Philipp
