Fix the loss of large, merged packets

[TheLostLambda]

A good thing I took a second look at this. Just bumping the read_buffer_size to the max allowed by the kernel solves the problem. One line in one file!

Wild how it can make so much of a difference...

Hey, that's awesome! Good job.
Maybe I misunderstand the read_buffer, but wouldn't we be missing smaller frames that come along? Or am I misunderstanding what the read_buffer means?

As I understand it, it's the sort of maximum size that it can read in. The default size is 4096, but during my debugging, I found that smaller ones were still let through. I think it just acts as a maximum size with the trade-off being more memory is allocated.

Sounds great. Doesn't seem to be using more resources in a noticeable way for me. Let's go for it.

Thank you very much for your hard work on this! Solid job.
