Since there are two 157 * ports, there are two of some GEnesis modules (e.g. two sets of 158 * DMA queues, two sets of FIFO control registers, etc...). Normally, 159 * the block for port 0 is at offset 0x0 and the block for port 1 is 160 * at offset 0x80 (i.e. the next page over). However for the transmit 161 * BMUs and RAMbuffers, there are two blocks for each port: one for 162 * the sync transmit queue and one for the async queue (which we don't 163 * use). However instead of ordering them like this: 164 * TX sync 1 / TX sync 2 / TX async 1 / TX async 2 165 * SysKonnect has instead ordered them like this: 166 * TX sync 1 / TX async 1 / TX sync 2 / TX async 2 167 * This means that when referencing the TX BMU and RAMbuffer registers, 168 * we have to double the block offset (0x80 * 2) in order to reach the 169 * second queue. This prevents us from using the same formula 170 * (sk_port * 0x80) to compute the offsets for all of the port-specific 171 * blocks: we need an extra offset for the BMU and RAMbuffer registers. 172 * The simplest thing is to provide an extra argument to these macros: 173 * the 'skip' parameter.
