Subject: Add 4 bytes to maximum frame length to allow for the frame checksum.
X-Git-Tag: v0.9.3~1269
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=52de4935f90b64da2c5d45917fa80e8f11509ad9;p=thirdparty%2Fipxe.git

Add 4 bytes to maximum frame length to allow for the frame checksum.
(This actually matters once you try using TCP, because you *will*
receive full-sized frames.)
