It was at some point I think :-) But at 8k it happens to fit on some intelish architectures in a common page of 8k (8192 bytes). I would not mind to see if much more configurable run-time -and- auto detecting compile time; we've got great improvements on some arch's with 16k pages -and- by fiddling with it so that it also happens to fit in a nice DMA multiple of the ethernetcard.
