a59a10dfeb drivers: Update timer APIs for Linux v6.15 
In Linux v6.15, the timer APIs hrtimer_init() and del_timer() have been
removed. The hrtimer_setup() was added in Linux v6.13 to replace
hrtimer_init() and hrtimer_init() have finally been removed. The
functions del_timer()/del_timer_sync() were renamed to
timer_delete()/timer_delete_sync() in Linux v6.15. Use conftest to
detect these changes and update the drivers as necessary.

11843f9878 nvethernet: fix Tx-ring full issue 
Issue: Below issue observed while running TCP_TX perf test
for longer duration.

nvethernet a808a10000.ethernet: [validate_ctx][1082][type:0x2][loga-0x84d2] dma_txrx: Invalid frame len
nvethernet a808a10000.ethernet mgbe0_0: Tx ring[0] is full
nvethernet a808a10000.ethernet mgbe0_0: Tx ring[0] is full
nvethernet a808910000.ethernet eqos_0: Tx ring[0] is full

This is a regression due to the below change -
https://git-master.nvidia.com/r/c/linux-nv-oot/+/3258684

The issue is that TSO packet is being treated as Non-TSO packet.
pskb_expand_head return code is returned directly where it can
return zero for TSO packet.

Fix:
Removed pskb_expand_head since headers are not getting updated in SW.
HW takes care performing the TSO handling. Also optimized the checks
in TSO path code.

8cb3f30c12 net: nvethernet: Fix build for Linux v6.15 
In Linux v6,15, a 'speed' argument was added to the phy_loopback()
function. Add a conftest test to detect this change and update the
nvethernet driver accordingly. Note that if 'speed' is set to 0 when
calling phy_loopback(), then phy_loopback() behaves the same way as it
did before this argument was added. So by default set speed to 0 for the
nvethernet driver.

955de38d70 net: nvethernet: Fix support for Linux v6.9 
When nvethernet was updated to support Linux v6.9 kernels, the code that
checks if the variable 'eee_req->advertised' is zero or non-zero was not
updated correctly. For Linux v6.9, the variable 'eee_req->advertised' is
a bitmask and so cannot be checked directly to see if it is zero or
non-zero. Building the nvethernet driver with the flag '-Werror=address'
exposed this issue. Fix this by using the 'linkmode_empty()' function to
determine if 'eee_req->advertised' is zero or non-zero for Linux v6.9
kernels.
