Support symmetric crypto ops, including AES, on hifn 7955 and 7956. Not tested on 795[56], but compiles and matches FreeBSD-tested diffs. Suggested by Sam Leffler <sam@errno.com>, as imported into FreeBSD by Sam. Submitted to FreeBSD by Rajesh Vaidyanath <RVaidyanath@hifn.com>.

Discard previous driver; it didnt really do anything. Replace with a new from-scratch port of recent OpenBSD hifn7751 source, with changes to the crypto-framework calls to fit Sam Leffler's rework. (Some of the attach-time changes from the previous driver were carried over). Many thanks to Quentin Garnier (cube@cubidou.net) for testing an pre-release of the driver and finding a couple of missing initializations. Note that RNG support is temporarily disabled, until a potential issue with RNG quality is investigated and resolved.

Many thanks to Quentin Garnier (cube@cubidou.net) for testing an pre-release of the driver and finding a couple of missing initializations.

Change pci_intr_map to get interrupt source information from a "struct pci_attach_args *" instead of from four separate parameters which in all cases were extracted from the same "struct pci_attach_args". This both simplifies the driver api, and allows for alternate PCI interrupt mapping schemes, such as one using the tables described in the Intel Multiprocessor Spec which describe interrupt wirings for devices behind pci-pci bridges based on the device's location rather the bridge's location.

hifn_write_4(struct hifn_softc *sc, int reggrp, bus_size_t reg, u_int32_t val)
Discard previous driver; it didnt really do anything. Replace with a new from-scratch port of recent OpenBSD hifn7751 source, with changes to the crypto-framework calls to fit Sam Leffler's rework. (Some of the attach-time changes from the previous driver were carried over). Many thanks to Quentin Garnier (cube@cubidou.net) for testing an pre-release of the driver and finding a couple of missing initializations. Note that RNG support is temporarily disabled, until a potential issue with RNG quality is investigated and resolved.
