Subject: [PATCH v2 2/2] Update documented default values for various TCP/UDP tunables

tcp_rmem and tcp_wmem use 1 page as default value for the minimum
amount of memory to be used, same as udp_wmem_min and udp_rmem_min.
Pages are different size on different architectures - use the right
units when describing the defaults.
