Hi,
I am trying to setup two Soekris 4521 with a minipci vpn1411 (Hi/fn 7955) in
a vpn.
I understood that the crypto card should automatically work with only three
kernel configuration file modification.
So I added these three lines
device crypto
device cryptodev
device hifn
I tested with openvpn (the one release with pkg_add). I used the default
cipher (I think this is BF-CBC - Blowfish 128 bit). The VPN works but I
didn't notice any difference in performance (with or without the crypto
card).
I also tested the crypto card with AES128 but the performance only got worse
(didn't have a baseline for that one)
Relevant output:
dmesg | grep hifn
hifn0 mem 0xa0000000-0xa0000fff,0xa0002000-0xa0003fff,0xa0008000-0xa000ffff
irq 10 at device 16.0 on pci0
hifn0: [ITHREAD]
hifn0: Hifn 7955, rev 0, 32KB dram, pll=0x801<ext clk, 4x mult>
dmesg | grep crypto
cryptosoft0: <software crypto> on motherboard

Any help would be appreciated
Unfortunately openssl doesn't use the accelerator by default. This
means all apps that use openssl likewise are not automatically
accelerated. I suggested a patch but it was not accepted. I can't
recall how you force openssl and/or consumers to use the device.
If you want to check whether the kernel support is working correctly
look in src/tools/tools/crypto for cryptotest and hifnstats.
