[Stgt-devel] iser patches

[Pete Wyckoff]

Here are the seven patches that make up the iSER changes.  They sit
on top of the previous six in the misc-fixes branch.

Full tree at git://git.osc.edu/tgt .  Please review, for eventual
inclusion in STGT.

Brief descriptions:

iser docs
    Single file in doc/, to explain the big picture of iSER and
    details of the implementation.

iser counter events
    RDMA interface cannot be driven by polling on fd.  This adds
    a new event management interface to tgtd.

iser transport buf
    Allocate in- and out-buffer space in transport always, not in
    valloc() in inquiry et al.

iser bidi alloc read buf
    Allocate read buffer for bidirectional commands in iscsi.

iser generalize iscsi
    Virtualize functions for memore management, event modification,
    RDMA read/write, pushing current implementations into TCP.

iser rounding
    Wire interface differences between iSCSI/TCP and iSER.

iser core
    Big iscsi_rdma.c file, build if ISCSI_RDMA=1.

Thanks,
