- <para>The TCP initial congestion window is used during the start of a TCP connection. During the start of a TCP
- session, when a client requests a resource, the server's initial congestion window determines how many data bytes
- will be sent during the initial burst of data. Takes a size in bytes between 1 and 4294967295 (2^32 - 1). The usual
- suffixes K, M, G are supported and are understood to the base of 1024. When unset, the kernel's default will be used.

- <para>The TCP initial advertised receive window is the amount of receive data (in bytes) that can initially be buffered at one time
- on a connection. The sending host can send only that amount of data before waiting for an acknowledgment and window update
- from the receiving host. Takes a size in bytes between 1 and 4294967295 (2^32 - 1). The usual suffixes K, M, G are supported
- and are understood to the base of 1024. When unset, the kernel's default will be used.
