PROBLEM:        (ZPOB30186, QAR 46022)          (Patch ID: OSF375-350221)
********
This patch fixes a halt/restart problem with the mfa driver ESP self-test.

If the DEMFA interface halts, self-tests are performed.  The mfareset routine
contained a bug which prevented the interface from restarting after the halt.

The DEMFA interface may also halt due to it's inability to allocate (malloc)
memory for it's buffers.  The correction for the malloc problem is contained
in the MANDATORY PATCH.

Typical error messages in the /var/adm/messages file will include:

        mfa: port halted (eintr): xber = 0x8a, xpst = 0xc1805,
        xpd1 = 0x183f8000, xpd2 = 0x0, xpud = 0x8c5d001c

The 'c' in the XPST indicates that the ESP special test failed.

If your system panics, your stack will look as follows:

        _XentMM()
        mfareset()
        mfainit()
        mfaioctl()
        in_ifinitia()
        in_control()
        udp_usrreq()
        ifioctl()
