Subject: Bump the netmgr quantum to 1024

Bump the netmgr quantum to 1024

During the stress testing, it was discovered that the default netmgr
quantum of 128 is not enough and there was a performance drop for TCP on
FreeBSD.  Bumping the default quantum to 1024 solves the performance
issue and is still enough to prevent the endless loops.
