John Baldwin dcfddc8dc0 cxgbe tom: Call t4_rcvd_locked from do_rx_data to return RX credits
In particular, the kernel RPC layer used by the NFS client never
invokes pru_rcvd since it always reads data from the socket upcall
via MSG_SOCALLBCK which avoids calling pru_rcvd.  As a result, on an
NFS client connection managed by t4_tom, RX credits were never
returned to the TOE connection to open the TCP window resulting in
connection hangs.

To fix, expand the set of conditions in do_rx_data where RX credits
are returned to match those in t4_rcvd_locked by calling the function
directly.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
