wifi: ath12k: Advertise multicast Ethernet encapsulation offload support

Browse source

Advertise IEEE80211_OFFLOAD_ENCAP_MCAST to inform mac80211 that
multicast frame encapsulation is handled in hardware. This allows
mac80211 to pass Ethernet-formatted multicast frames directly to
the driver.

In ath12k_wifi7_mac_op_tx(), refine the logic that selects the MLO
multicast replication path. Add a sta pointer check so that only unicast
Hardware-encap frames use the direct transmit path, while multicast
Hardware-encap frames fall through to the MLO replication loop and are
transmitted on each active link.

In the MLO replication loop, use skb_clone() for Hardware-encap frames.
These frames are already in Ethernet format and do not require
802.11 link address rewriting by ath12k_mlo_mcast_update_tx_link_address().

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
