Both bond_alb_xmit() and bond_tlb_xmit() produce a valid warning with
gcc-13:
  drivers/net/bonding/bond_alb.c:1409:13: error: conflicting types for 'bond_tlb_xmit' due to enum/integer mismatch; have 'netdev_tx_t(struct sk_buff *, struct net_device *)' ...
  include/net/bond_alb.h:160:5: note: previous declaration of 'bond_tlb_xmit' with type 'int(struct sk_buff *, struct net_device *)'

  drivers/net/bonding/bond_alb.c:1523:13: error: conflicting types for 'bond_alb_xmit' due to enum/integer mismatch; have 'netdev_tx_t(struct sk_buff *, struct net_device *)' ...
  include/net/bond_alb.h:159:5: note: previous declaration of 'bond_alb_xmit' with type 'int(struct sk_buff *, struct net_device *)'

I.e. the return type of the declaration is int, while the definitions
spell netdev_tx_t. Synchronize both of them to the latter.
