Normally, * the block for port 0 is at offset 0x0 and the block for port 1 is * at offset 0x80 (i.e. the next page over). However for the transmit * BMUs and RAMbuffers, there are two blocks for each port: one for * the sync transmit queue and one for the async queue (which we don't * use). However instead of ordering them like this: * TX sync 1 / TX sync 2 / TX async 1 / TX async 2 * SysKonnect has instead ordered them like this: * TX sync 1 / TX async 1 / TX sync 2 / TX async 2 * This means that when referencing the TX BMU and RAMbuffer registers, * we have to double the block offset (0x80 * 2) in order to reach the * second queue. This prevents us from using the same formula * (sk_port * 0x80) to compute the offsets for all of the port-specific * blocks: we need an extra offset for the BMU and RAMbuffer registers. * The simplest thing is to provide an extra argument to these macros: * the 'skip' parameter. The 'skip' value is the number of extra pages * for skip when computing the port0/port1 offsets. For most registers, * the skip value is 0; for the BMU and RAMbuffer registers, it's 1. */ #define SK_IF_READ_4(sc_if, skip, reg) \ sk_win_read_4(sc_if->sk_softc, reg + \ ((sc_if->sk_port * (skip +
