- The previous fix for STRCPY introduced a new bug. STRCPY must always
copy the final NULL terminator of the string, but must NOT increment
the source or destination pointers for the NULL terminator.
- The CTC simulation did not correctly support streaming mode, which
can in some cases request reads that are not on 512-byte block
boundaries.
- To begin to support System V Release 4 UNIX, the NI card (called EMD
under SVR4) needed to support several more CRC codes for pump code.
Previously, the NI ethernet device expected to do all
autoconfiguration at attach time. Furthermore, if attaching failed for
some reason (e.g., permission issues on a tap device, etc.) the card
would be left autoconfigured, but in a broken state that could lead to
reading uninitialized memory.
This change fixes those bugs, and allows the device to be attached and
detached more freely. The card is now autoconfigured when it is
enabled. Attaching and detaching are analogous to connecting or
disconnecting an ethernet transceiver from the physical device.
This change also addresses some unused function parameter warnings
issued by GNU Flycheck (not generally used by the build process, but
useful when editing files with Flycheck enabled)
