 * roce_hw_index_cmp_lt - Compare two hardware index values in hisilicon
 *                        SOC, check if a is less than b.
 * @a: hardware index value
 * @b: hardware index value
 * @bits: the number of bits of a and b, range: 0~31.
 *
 * Hardware index increases continuously till max value, and then restart
 * from zero, again and again. Because the bits of reg field is often
 * limited, the reg field can only hold the low bits of the hardware index
 * in hisilicon SOC.
 * In some scenes we need to compare two values(a,b) getted from two reg
 * fields in this driver, for example:
 * If a equals 0xfffe, b equals 0x1 and bits equals 16, we think b has
 * incresed from 0xffff to 0x1 and a is less than b.
 * If a equals 0xfffe, b equals 0x0xf001 and bits equals 16, we think a
 * is bigger than b.
 *
 * Return true on a less than b, otherwise false.
