That's a modified version of a modified driver...

That makes it difficult to figure out if you are getting a high incoming
packet rate, or if there are a small number packets such as "frag bombs"
that consume disproportionate CPU time.

Yes, it's very difficult to find info on what the parameters are, what
they do, and suggested settings for different circumstances. You would
think that anyone that changes the interface should also be responsible
for documenting the new interface, but that's not how it works...
The best guide I've found, without just reading the source code, is

What is reported in /proc/net/dev? The 'ifconfig' program reads the raw
values from there, and then discards or summarizes the error fields. We
need to know what type of errors these are.
If you are using a recent version of my driver release, you can
selectively enable driver status/error messages using
mii-diag eth0 --msg-level <value>
where <value> is the sum of
NETIF_MSG_DRV = 0x0001,
NETIF_MSG_PROBE = 0x0002,
NETIF_MSG_LINK = 0x0004,
NETIF_MSG_TIMER = 0x0008,
NETIF_MSG_IFDOWN = 0x0010,
NETIF_MSG_IFUP = 0x0020,

NETIF_MSG_INTR = 0x0200,
NETIF_MSG_TX_DONE = 0x0400,
NETIF_MSG_RX_STATUS = 0x0800,
NETIF_MSG_PKTDATA = 0x1000,
