However - * the rx rings do not need to contain a static number of buffer - * descriptors, thus it makes sense to move the memory allocation out - * of the main interrupt handler and do it in a bottom half handler - * and only allocate new buffers when the number of buffers in the - * ring is below a certain threshold. In order to avoid starving the - * NIC under heavy load it is however necessary to force allocation - * when hitting a minimum threshold. The strategy for alloction is as - * follows: - * - * RX_LOW_BUF_THRES - allocate buffers in the bottom half - * RX_PANIC_LOW_THRES - we are very low on buffers, allocate - * the buffers in the interrupt handler - * RX_RING_THRES - maximum number of buffers in the rx ring - * - * One advantagous side effect of this allocation approach is that the - * entire rx processing can be done without holding any spin lock - * since the rx rings and registers are totally independent of the tx - * ring and its registers. This of course includes the kmalloc's of - * new skb's. Thus start_xmit can run in parallel with rx processing - * and the memory allocation on SMP systems. - * - * Note that running the skb reallocation in a bottom half opens up - * another can of races which needs to be handled properly. In - * particular it can happen that the interrupt handler tries to run - * the reallocation while the bottom half is either running on another - * CPU or was interrupted on the same CPU. To get around this the - * driver uses bitops to prevent the reallocation routines from being - * reentered. - * - * TX handling can also be done without holding any spin lock, wheee - * this is fun! since tx_csm is only written to by the interrupt - * handler. - */ - -/* - * Threshold values for RX buffer allocation - the low water marks for - * when to start refilling the rings are set to 75% of the ring - * sizes. It seems to make sense to refill the rings entirely from the - * intrrupt handler once it gets below the panic threshold, that way - * we don't risk that the refilling is moved to another CPU when the - * one running the interrupt handler just got the slab code hot in its - * cache. - */ -#define RX_RING_SIZE AR2313_DESCR_ENTRIES -#define RX_PANIC_THRES (RX_RING_SIZE/4) -#define RX_LOW_THRES ((3*RX_RING_SIZE)/4) -#define CRC_LEN 4 -#define RX_OFFSET 2 - -#define AR2313_BUFSIZE (AR2313_MTU + ETH_HLEN + CRC_LEN + RX_OFFSET) - -#ifdef MODULE -MODULE_AUTHOR("Sameer Dekate<sdekate@arubanetworks.com>"); -MODULE_DESCRIPTION("AR2313 Ethernet driver"); -#endif - -#if DEBUG -static char version[] __initdata = - "ar2313.c: v0.02 2006/06/19 sdekate@arubanetworks.com\n"; -#endif /* DEBUG */ - -#define virt_to_phys(x) ((u32)(x) & 0x1fffffff) - -// prototypes -static short armiiread(short phy, short reg); -static void armiiwrite(short phy, short reg, short data); -#ifdef TX_TIMEOUT -static void ar2313_tx_timeout(struct net_device *dev); -#endif -static void ar2313_halt(struct net_device *dev); -static void rx_tasklet_func(unsigned long data); -static void ar2313_multicast_list(struct net_device *dev); - -static struct net_device *root_dev; -static int probed __initdata = 0; -static unsigned long ar_eth_base; -static unsigned long ar_dma_base; -static unsigned long ar_int_base; -static unsigned long ar_int_mac_mask; -static unsigned long ar_int_phy_mask; - -#ifndef ERR -#define ERR(fmt, args...) printk("%s: " fmt, __func__, ##args) -#endif - -static int parse_mac_addr(struct net_device *dev, char* macstr){ - int i, j; - unsigned char result, value; - - for (i=0; i<6; i++) { - result = 0; - if (i != 5 && *(macstr+2) != ':') { - ERR("invalid mac address format: %d %c\n", - i, *(macstr+2)); - return -EINVAL; - } - for (j=0; j<2; j++) { - if (isxdigit(*macstr) && (value = isdigit(*macstr) ?
