Fix a lock-order reversal in the net driver by dropping the lock and holding a reference prior to calling further into the hyperv stack. Added missing FreeBSD idents. Submitted by: Microsoft hyperv dev team Approved by: re@ (gjb)

hyperv/hn: Improve sending performance - Avoid main lock contention by trylock for if_start, if that fails, schedule TX taskqueue for if_start - Don't do direct sending if the packet to be sent is large, e.g. TSO packet. This change gives me stable 9.1Gbps TCP sending performance w/ TSO over a 10Gbe directly connected network (the performance fluctuated between 4Gbps and 9Gbps before this commit). It also improves non- TSO TCP sending performance a lot. Reviewed by: adrian, royger Approved by: adrian (mentor) Sponsored by: Microsoft OSTC Differential Revision: https://reviews.freebsd.org/D5074

This 5 times the performance during TCP sending test, when there is one bpf(4) attached. - Allow size of chimney sending be tuned on a running system.

hyperv/hn: Implement LRO - Implement the LRO using tcp_lro APIs, and LRO is enabled by default. - Add several stats sysctl nodes. - Check IP/TCP length before sending the packet to tcp_lro_rx(), if host does not provide RX csum information (*); and add an option through sysctl to always trust host TCP segment csum checks (default is off). - Add sysctl to control the LRO entry depth; it is disabled by default. It is used to avoid holding too much TCP segments in driver. Limiting the LRO entry depth helps a lot in a one/two streams RX test. This one 3x the RX performance on my local test (3Gbps -> 10Gbps), and ~2x the RX performance over a directly connected 40Ge network (5Gbps -> 9Gbps). (*) It seems the host stops supplying csum information, once the network load is high. This still needs investigation...
