77  * Compute offset of port-specific register. 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.
