For safety I was trying to clear out the descriptor but the full descriptor
was not allocated.  Remove any code trying to do that so the same mistake
won't be made.  This was found when looking to MFC the prior change
and having the loader, load the module.

Remove cq->ntxqsets since the completion queue is part of the RX and TX sets
enic(4): fix down/up, MTU changes and more 2025-01-09T16:52:54+00:00 Doug Ambrisko ambrisko@FreeBSD.org 2025-01-09T16:28:37+00:00 0acab8b3d1336d4db73a9946ef76b4bcd0b0aabe ifconfig down/up cycles was not working. Fix that which is required to support MTU changes. Now doing ifconfig enic0 mtu 3000 for example works. If the MTU is changes in the VIC HW configuration, that is not reflected in and the OS reports the default 1500. I need to look at that but changing it via ifconfig works. So this is different then what Linux does. Change TX interrupt allocation to be in this driver. Change the admin interrupt count to 2. This make multiple queues work but need to be done as pairs so if the VIC has more TX or RX queues setup in the VIC configuration it will use the lesser value. While updating the TX interrupt also add support for devcmd2. Enable checksum offloading. PR: 282095

Change TX interrupt allocation to be in this driver.  Change the admin
interrupt count to 2.  This make multiple queues work but need to be
done as pairs so if the VIC has more TX or RX queues setup in the
VIC configuration it will use the lesser value.

While updating the TX interrupt also add support for devcmd2.

Enable checksum offloading.

This driver is based of the enic (Cisco VIC) DPDK driver.  It provides
basic ethernet functionality.  Has been run with various VIC cards to
do UEFI PXE boot with NFS root.
