It's not important, but in case you are creating another version of the
patch, maybe the allowed range can be extended somewhat. The example values
I picked when I sent my suggestion were really made up. It's great if
they work fine, but users might want to  tune this far more depending on
their workloads,  How about these

#define HIP04_MAX_TX_COALESCE_USECS    100000
#define HIP04_MIN_TX_COALESCE_USECS    1
#define HIP04_MAX_TX_COALESCE_FRAMES   (TX_DESC_NUM - 1)
#define HIP04_MIN_TX_COALESCE_FRAMES   1
