[PATCH] net/ice: add MAC anti-spoof disable option

[Anurag Mandal]

VRRP advertisement packets are dropped as TX-errors upon transmission from
a vsi of ice PF due to MAC anti-spoof check. There is no way to disable
this check in the Tx direction to avoid these packets being dropped.

This patch introduces devarg "mac-anti-spoof-disable" to allow user to
disable MAC anti-spoof check. Disable MAC Anti-spoof check in the Tx
direction to avoid getting dropped as TX-errors upon packet transmission
when their source MAC address matches one of the MAC addresses assigned
to that same NIC port.

I dislike as a point of principle having options with "disable" in the
name, because it means that the normal logic for on/off is reversed. For
example, in this case to enable anti-spoof you set it to 0. Also, having
disable in the name makes the name longer!

How about having this setting called "mac-anti-spoof" and setting the
default to 1.

If the source prune feature conflicts with the anti-spoof one in some way,
then we need to check at devargs processing time for conflicts and warn the
user. Also, if the user specifies on flag which changes the default of the
other, a logging message should be emitted (e.g. at INFO or NOTICE level)

This seems strange to me. When anti-spoof disable flag is set, we turn on
the ENA (enable, right?) MAC_ANTI_SPOOF flag?

[PATCH v2] net/ice: add MAC anti-spoof option

[Anurag Mandal]

VRRP advertisement packets are dropped as TX-errors upon transmission from
a vsi of ice PF due to MAC anti-spoof check which is enabled by default.
There is no way to disable this check in the Tx direction to avoid
these packets being dropped.

This patch introduces devargs "mac-anti-spoof" to allow user to
disable MAC anti-spoof check. Disable MAC Anti-spoof check
in the Tx direction to avoid getting dropped as TX-errors upon packet
transmission when their source MAC address matches one of the MAC
addresses assigned to that same NIC port.

V2: Addressed Bruce Richardson's feedback
 - changed devargs name to "mac-anti-spoof"
 - changed devargs member name to "mac_anti_spoof"
 - changed macro name to "ICE_MAC_ANTI_SPOOF_ARG"
 - set the default value of the devargs to 1
 - added NOTICE log msg when MAC Anti-spoof is disabled
 - added more code comments to provide clarity
 - fixed typo error with ICE_AQ_VSI_SEC_FLAG_ENA_MAC_ANTI_SPOOF

This is the same story as with Source Prune.
Please disable source-prune filtering by default, and provide an option to enable it.
Also, suggest shortening the devargs name to simply "anti-spoof", like "source-prune"; they both operate on MAC basis.

Let's make something generic instead, to replace those silly devargs.
We have individual Ethdev APIs to enable/disable various Rx filtering, e.g. "promiscuous", "all multicast".
Obviously, we don't want to introduce new APIs for every semi-exotic filter any NIC may offer, like "source prune" and "anti spoof", but we could introduce a set of generic Ethdev APIs to support filters such as these, using a bitfield enum. E.g.:

/* Enable one or more filters. */
int rte_ethdev_filter_enable(uin16_t port_id, uint64_t filter);

/* Disable one or more filters. */
int rte_ethdev_filter_disable(uin16_t port_id, uint64_t filter);

/* Get bit field of filters enabled. */
int64_t rte_ethdev_filter_get(uin16_t port_id);

/* Get bit field of filters supported by device. */
int64_t rte_ethdev_filter_capa(uin16_t port_id); /**/

/** Destination MAC must match NIC's MAC address.
 * (This is the inverse of Promiscuous.)
 * Default enabled.
 */
#define RTE_ETH_FILTER_RX_NON_PROMISC RTE_BIT64(0)
/** Multicast Hash.
 * (This is the inverse of All Multicast.)
 * Default enabled.
 */
#define RTE_ETH_FILTER_RX_MULTICAST RTE_BIT64(1)
/** Source Prune.
 * [Insert description here.]
 */
#define RTE_ETH_FILTER_RX_SOURCE_PRUNE RTE_BIT64(2)
/* Add new Rx filters here, in increasing order. */
/* Add new Tx filters here, in decreasing order. */
/** Anti-Spoof.
 * [Insert description here.]
 */
#define RTE_ETH_FILTER_RX_SOURCE_PRUNE RTE_BIT64(62)
