Hi Bernd,

The NetOctave NSP2000 is a crypto-acceleration card that accelerates  
RNG, Public Key (D-H, RSA, DSA), SSL, TLS,  and IPSec.  The driver is  
integrated with the opencrypto framework to provide hardware offload  
for the following operations:

Encryption:
CRYPTO_DES_CBC
CRYPTO_3DES_CBC
CRYPTO_MD5
CRYPTO_SHA1
CRYPTO_MD5_HMAC
CRYPTO_SHA1_HMAC

Key operations:
CRK_MOD_EXP
CRK_DSA_SIGN
CRK_DSA_VERIFY
CRK_DH_COMPUTE_KEY
CRK_MOD_ADD
CRK_MOD_ADDINV
CRK_MOD_SUB
CRK_MOD_MULT
CRK_MOD_MULTINV
CRK_MOD

There are a number of files present in the commit that are not yet  
ported and implement kernel and user APIs to directly use the card  
features.  I included them because they are part of the source donated  
to NetBSD by the original developer, and they may be of use for non- 
opencrypto applications (e.g ports of existing NetOctave applications).

The driver functions fine without the entry in pcidevs, but thank you  
for bringing that to my attention.  Are the pcidevs.h and  
pcidevs_data.h headers critical to the driver system?  I didn't think  
so, but I can update pcidevs if it is required.  Tools such as lcpci  
obtain their information from the usual pci.ids file, which does have  
an entry for NetOctave.

The term "n8" comes from NetOctave, a reduction of "Net" and "Oct" to  
"N" & "8".

Regards,
Darran.
