No offence here but the generic hdlc layer's been always confusing. I will write here what I believe is going on. Until version 2.4.20 we had the old hdlc layer, with only one source file hdlc.c. People that wanted to use the new hdlc layer had to apply a patch provided by Halasa or by the WAN cards vendors. The kernel 2.4.21 came out with the new hdlc layer, that includes a couple of files: hdlc_generic.c, hdlc_fr.c, hdlc_ppp.c, hdlc_raw.c, etc. I don't know the status of the -ac tree but I can say that the kernel 2.4.21 has the new code. The new hdlc layer really needs new tools. This new tool can (supposedly) be found at Halasa's web site. I don't know if someone has tested these tools but I am about to run a test this afternoon. If someone is interested on the results, just drop me a line. regards Henrique ----- Original Message ----- From: "Alan Cox" To: "Henrique Oliveira" Cc: "Marcelo Tosatti" ; "Kevin Curtis" ; "lkml" Sent: Friday, July 11, 2003 2:12 AM Subject: Re: Why is generic hldc beig ignored?

As I understand it the new hdlc layer needs newer tools ? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
