Since there are two 78 * ports, there are two of some GEnesis modules (e.g. two sets of 79 * DMA queues, two sets of FIFO control registers, etc...). Normally, 80 * the block for port 0 is at offset 0x0 and the block for port 1 is 81 * at offset 0x80 (i.e. the next page over). However for the transmit 82 * BMUs and RAMbuffers, there are two blocks for each port: one for 83 * the sync transmit queue and one for the async queue (which we don't 84 * use). However instead of ordering them like this: 85 * TX sync 1 / TX sync 2 / TX async 1 / TX async 2 86 * SysKonnect has instead ordered them like this: 87 * TX sync 1 / TX async 1 / TX sync 2 / TX async 2 88 * This means that when referencing the TX BMU and RAMbuffer registers, 89 * we have to double the block offset (0x80 * 2) in order to reach the 90 * second queue. This prevents us from using the same formula 91 * (sk_port * 0x80) to compute the offsets for all of the port-specific 92 * blocks: we need an extra offset for the BMU and RAMbuffer registers. 93 * The simplest thing is to provide an extra argument to these macros: 94 * the 'skip' parameter. The 'skip' value is the number of extra pages 95 * for skip when computing the port0/port1 offsets. For most registers, 96 * the skip value is 0; for the BMU and RAMbuffer registers, it's 1. 97 */ 98#define SK_IF_READ_4(sc_if, skip, reg) \ 99 sk_win_read_4(sc_if->sk_softc, reg + \ 100
