Those portions are... - * Copyright (c) 1996, 1997, 1998, 1999 Mark Tinguely - * All rights reserved. - * - ****************************************************************************** - * - * This driver supports the Fore LE155, LE25, and IDT 77211 cards. - * - * ATM CBR connections are supported, and bandwidth is allocated in - * slots of 64k each. Three VBR queues handle traffic for VBR and - * UBR. Two UBR queues prioritize UBR traffic. ILMI and signalling - * get the higher priority queue, as well as UBR traffic that specifies - * a peak cell rate. All other UBR traffic goes into the lower queue. - * - ****************************************************************************** - * - * The following sysctl variables are used: - * - * hw.idt.log_bufstat (0) Log free buffers (every few minutes) - * hw.idt.log_vcs (0) Log VC opens, closes, and other events - * hw.idt.bufs_large (100) Max/target number of free 2k buffers - * hw.idt.bufs_small (200) Max/target number of free mbufs - * hw.idt.cur_large (R/O) Current number of free 2k buffers - * hw.idt.cur_small (R/O) Current number of free mbufs - * hw.idt.qptr_hold (1) Optimize TX queue buffer for lowest overhead - * - * Note that the read-only buffer counts will not work with multiple cards. - * - ****************************************************************************** - * - * Assumptions: - * - * 1. All mbuf clusters are 2048 bytes, and aligned. - * 2. All mbufs are 256 bytes, and aligned (see idt_intr_tsq). - * - * Bugs: - * - * 1. Function idt_detach() is unusuable because idt_release_mem() is - * incomplete. The mbufs held in the free buffer queues can be - * recovered from the "mcheck" hash table. - * 2. The memory allocation could be cleaned up quite a bit. - * - ****************************************************************************** - */ - -#include <sys/cdefs.h> -__FBSDID("$FreeBSD$"); - -#include <sys/param.h> -#include <sys/systm.h> -#include <sys/conf.h> -#include <sys/mbuf.h> -#include <sys/protosw.h> -#include <sys/socket.h> -#include <sys/sysctl.h> - -#include <sys/sockio.h> - -#include <sys/errno.h> -#include <sys/malloc.h> -#include <sys/kernel.h> -#include <sys/proc.h> -#include <sys/signalvar.h> -#include <sys/mman.h> -#include <machine/cpu.h> /* bootverbose */ - -#include <sys/bus.h> -#include <machine/bus.h> -#include <sys/rman.h> -#include <machine/resource.h> - -#include <net/if.h> -#include <net/if_arp.h> - -/* Gross kludge to make lint compile again.

The buffer length must not be zero. - * 2. The buffer length must be a multiple of four bytes. - * 3. The sum of the buffer lengths must be a multiple of 48 bytes if - * it is a CS-PDU (eg AAL5). - * 4. All buffers for a CS-PDU must be contiguous and grouped (no other - * PDU buffers or even TSRs). - * 5. For AAL5 PDUs, the buffer lengths must include 8 bytes for the - * AAL5 length/control and CRC fields. - * 6. For AAL5 PDUs, the buffer length of the last buffer must be > 8 bytes. - * 7. For AAL5 PDUs, all buffers containing bytes for the last cell must - * have the END_CS_PDU bit set to 1. - * - * Also, from the IDT applications note ("FAQ") 77211_AN_97088.pdf file: - * Page 5, under "General Technical Questions" (copied EXACTLY): - * - * 5). Can the NicStar begin segmentation from a non-word aligned buffer? - * No, the transmit buffer must point to a word aligned buffer. - * - * Since the buffers MUST be word aligned and MUST be word lengths, we have - * two potential problems with M_EXT mbufs: - * - * 1. If the M_EXT mbuf has a non word aligned address, we have to copy - * the whole thing to a fresh buffer. Unless - the previous mbuf is - * not M_EXT, and it is short by exactly the same amount. Unlikely. - * - * 2. If the M_EXT mbuf has a non word length, we have to push those bytes - * to the next mbuf. If the next mbuf is also M_EXT, we are stuck. - * Unless - the extra bytes from both mbufs are exactly 4 bytes. Then - * we can MGET an empty buf to splice in between. - * - * Also, these rules mean that if any buffer is not word-length, all of the - * following buffers will need to be copied/shifted, unless one or more have - * lengths off by the right amount to fix the earlier buffer. - * - ******************************************************************************* - * - * Put mbuf chain on transmit queue - * - * in: IDT device, mbuf chain, vpi, vci, flags (2 MPEG2 TS == 8 AAL5 cells) - * out: (nothing) - * - * Date first: 11/08/2000 last: 05/30/2000 - */ - -void -idt_transmit(IDT * idt, struct mbuf * mfirst, int vpi, int vci, int flags) -{ - CONNECTION *connection; - struct mbuf *m1, *m0, *malign, *msend; - int tot_size, tot_scq, x; - int this_len; - int padding; - - connection = idt_connect_find(idt, vpi, vci); - if (connection == NULL) { /* this VPI/VCI not open */ - idt_transmit_drop(idt, mfirst); - return; - } - if (connection->queue == NULL) { - idt_transmit_drop(idt, mfirst); - connection->vccinf->vc_oerrors++; - return; - } - if (flags) - connection->flg_mpeg2ts = 1; - else - connection->flg_mpeg2ts = 0; - - /* - * New strategy: assume that all the buffers are aligned and word - * length.
