be2net: Add description about various RSS hash types 



Incorporated review comment from Eric Dumazet. Added description
about different RSS hash types which adapter is capable of.
Will add support for ETHTOOL_GRXFH and ETHTOOL_SRXFX as suggested
by Ben Hutchings in a later patch.

/* RSS type		Input parameters used to compute RX hash

 * RSS_ENABLE_IPV4	SRC IPv4, DST IPv4

 * RSS_ENABLE_TCP_IPV4	SRC IPv4, DST IPv4, TCP SRC PORT, TCP DST PORT

 * RSS_ENABLE_IPV6	SRC IPv6, DST IPv6

 * RSS_ENABLE_TCP_IPV6	SRC IPv6, DST IPv6, TCP SRC PORT, TCP DST PORT

 * RSS_ENABLE_UDP_IPV4	SRC IPv4, DST IPv4, UDP SRC PORT, UDP DST PORT

 * RSS_ENABLE_UDP_IPV6	SRC IPv6, DST IPv6, UDP SRC PORT, UDP DST PORT

 *

 * When multiple RSS types are enabled, HW picks the best hash policy

 * based on the type of the received packet.
